What are the most popular JS libraries for 2019? There are about 50 of them but we’ll take only the top ones. You will have no problems with searching developers and developing complex projects for your business.

Node.js

One more popular JS framework is Node.js. What you get when using it is an event-driven input/output, lightweight real-time apps that work on any platform. You can develop a scalable application that will easily cope with a great number of connections. You don’t lose page speed load and you get a handy scalability.

Strong points:

• Processing a big number of requests at the same time
• A quite big and rushing community with a lot of code samples
• It makes JS a full-stack tool
• You can create any element from scratch

Weak points:

• There were cases of an unstable API
• There isn’t multi-thread request handling

Node.js is a good choice for fast data streaming applications thanks to its nonblocking features. You get a high performance and quality of the product.

Vue.js

This is the top JS front-side tool that people kindly name as the baby of Angular and React. You can use it for a simple and fast development of the interface part of the software. Its advantages are two-way data binding and rendering data on the server side. Vue has some strong and weak points that we will list below.

Strong points:

• Fast spread. More and more businesses choose Vue to be the stack to use
• It’s easy to learn. There’s a little time required for getting started with the Vue
• It’s easy to integrate with other web elements and technologies
• Declarative rendering support

Weak points:

• A little number of available resources
• A small community in comparison with Angular or React

It’s a simple tool for fast and efficient product release. If you don’t need complex solutions or some specific features for your project. Vue.js is the right choice for you.

Angular.js

This is the most powerful front-side JS framework. What you get with it are fast coding, easy testing, two-sided data binding that will help you see any changes or updates on the server side in no time. What are strong and weak points of this framework?

Strong points:

• You can develop a PWA site
• High-quality support by Google team
• Two-sided data binding
• Advance mobile web development

Weak points:

• Battery consuming apps
• Requires optimization for removing problems with performance
• It’s hard to learn

If you need a solution for developing a complex project with a lot of elements that should work correctly on any device, Angular.js is a good choice for you. There’s a big number of certified developers and a big community that allows you to create the right product to meet your business goals.

Develop your product with JS

Strong community, a lot of ready solutions make three JS frameworks the most popular ones. They’re good for building projects of various complexity and in a short time. You can benefit more if you hire an outsourcing team that will also save your costs.

Codemotion is a team of JavaScript ninjas. We analyze your business needs and pick up the right solution for them. What we have is a group of popular frameworks that we can use for any type of the project. What you get is a quick MVP launch, time and cost efficiency.

The post 3 top JS frameworks to be used in 2019 appeared first on Codemotion.

I started googling this question and I saw that I was not the only one who tried to make this hard choice. There were opposite opinions and positions to this question that were a bit confusing. That’s why I’m going to guide you through the process of making a decision by me to make your life a bit easier and happier.

The definition

You can develop a Native application for one platform only. We know about the two most popular platforms these days such as iOS and Android. Therefore, you will use the Xcode for creating apps for iOS. And for Android, you will use the Android Studio. I guess that’s easy to understand.

React Native is a framework. You will see the signs of web development tools that have merged into the mobile development ones. You will need Javascript for building the software. However, you will also result into a native application.

I had the task to build an application for the two platforms, so I was thinking to use React Native. I was planning to develop only one application for two platforms. I planned to have one code that I could use for these systems. But I thought it to be to good to be truth. One code that could even adjust the visual elements for the platforms seemed unreal. So I decided to find out more.

Native Advantages

Api access

You can go on using the native environment to get access to all the APIs and all the tools. You won’t see any additional mappings of the layer when we talk about the updates of the functionality. You won’t see any dependencies or constraints that you were used to see in the native environment.

Other libraries

You will have a wide choice of libraries that you can use in the native environment thanks to the big public that will always help you build the application with ease. You will have the chance to improve your experience and your software as well.

Knowledge is power

If you are good at using a native language, you will have a good knowledge of the architecture. You cannot add all the required functionality through the framework, so I can admit that your knowledge is a real power here.

Take a look into the future

When considering the development of the application in three or five years, choosing the native language may become a safe option. You should also be ready for some possible changes like  the one with Objective-C and Swift that Apple did some time ago. However, this shouldn’t worry you too much as there were instructions on how to shift. You can feel safe as there’s a motivation to keep the platform updated.

Language rules

We can easily call native languages as the strict ones because we can easily detect all the errors. You can use all of them to develop software for iOS and Android. And there’s one good thing about them. You can learn them with ease. However, you will need some time to feel ok to use them.

Native Disadvantages

You need to build two apps

There’s one rule that can spoil all the impression from the native languages. You can run one app only on one platform. The result of using a native language is quiet predictive. You will create two separate apps for two systems. And they won’t look the same. And they won’t be alike. But don’t worry, you can have one backend for the two of them.

React Native Advantages

One application

As you may guess, you don’t have to build two or more applications for all the platforms. You take one code base and use it for iOS and Android. There’s no need to learn all those languages.

Save time

If your application is quite simple, you will save the precious time from the start to the publishing moment. And you can get more profit if you make your app ready on time.

Transition from web

You may face some problems or obstacles when moving from web to mobile development. If you know at least something about the Javascript frameworks, you will experience this transition with the minimum pain. You will spend little time learning all the things for crafting the software.

High speed

When you save the file in React Native, you can see all the changes on the mobile device in real time. You will greatly make the process of the app development faster.

Free to use

You will see an open source that gives you a chance to view the code. You can do anything with it starting from a simple attempt to understand how everything works to fixing all the bugs that you can ever notice.

React Native Disadvantages

A limited number of APIs

There’s one thing that may disappoint you. Not all the APIs are supported by React. The number of supported APIs is quite impressing, but you can face the situation when you have to get access to another API or use another functionality. But you can still use some native modules for these purposes.

Modules

You don’t get all the functionality together with React, but you can use Native Modules if needed. They are all written with the help of the native language. So you need to have at least the basic knowledge of languages and how to deal with them. If you have chosen React not to work with languages, you will feel uncomfortable in such situations. And you will make two codes for different platforms as well.

Other libraries

You won’t find many libraries that you can use with React. The public is growing, but the number of participants is little. You can use native modules if you want to use the libraries that were created for the platform.

Access to other apps

If you want to create software that will require the access to some apps like a camera, you won’t be able to use the framework for this purpose. You will need to use modules or other libraries as React doesn’t support all of these things.

Visuals

To make all graphic elements work correctly and make them display the right way, you will have to make too many if-phrases or even separate your code to meet the requirements of both platforms. As you know. The design of Android is different from iOS.

Take a look into the future

You don’t have any guarantee that React will be supported in five years or so. There can be one day when Facebook just stops updating this framework and that’s it. What will you do in this case?

The decision that I’ve come to

If you want to create a simple app is a short period of time for both systems, you can choose React Native. It suits these goals just perfectly. You can choose if you have had any experience in web programming.

If you have any other situation, it’s always better to choose Native. You will need some basic understanding of native languages even when crafting software with React. If these are your first steps in coding, I strongly recommend you native languages.

It was really complicated to make the right decision for me. My task was to build software that should contain some advanced functionality. And this app should be for both systems. There was one more thing about the maintenance in the future. React was a more preferable choice here.

However, I’m only learning to become a great iOS programmer. I have some experience using Swift and I like it a lot. As it’s only the beginning of my pathway, there’s lots more to learn and practice before I can be proud of being an iOS programmer. I had people around me who could assist me with learning and using the native languages.

After long hours of thinking, comparing and analyzing, I finally made my choice. I stopped at the native solution. If I wasn’t developing for iOS, I could have chosen another way. But now I can say for sure that the result of my choice will lead me to being a real pro.

Why should you choose AngularJS for your web app?

Users get a super positive experience when the data on the page is updated every single moment, which is a perfect solution for an online store, newsfeed website or any other web app with the dynamic content.

Simplicity is a key word for describing the development process and testing. You get little code thanks to dependency injection and data binding. You can reuse and update them with ease. Modularity will let you divide a huge project into well-structured milestones. AngularJS can make developers’ workflow easier thanks to a big number of tools and support from the Google team.

A remote developer or a team of developers will provide you with efficient communication and workflow. Cooperation with an AngularJS development company in Ukraine is the best choice for building a new project that will give you fast results, high quality of work and cost efficiency.

AngularJS: features and specs

AngularJS comprises AJAX and DOM coding approaches and fits them into a specific structure. You will find this framework opinionated regarding the Create-Read-Update-Delete workflow for developing a new application. This opinion may easily become a starting point that you can update and change for a new project. AngularJS provides developers with directives, data-binding technology, form validation, reusable components, deep-linking and dependency injection, tools for testing and running the app.

MVC Architecture

Model-View-Controller serves to split the project into small and manageable structures. The Model stands for standard JavaScript objects that users interact with. The View is all about DOM and the Controller is responsible for the business logic.

Two Way Data Binding

It’s a super handy tool to get rid of 80% of the code in comparison with standard web development. The ng-model binds the model and the view. A developer updates the model and the view is also changed respectively. And vice versa.

Templates

It’s an old HTML with some extra markup. Developers parse the HTML code into DOM that they use in the AngularJS compiler. It’s a handy feature that lets designers make edits right in the HTML code and give it to developers for rendering directives that set up the data binding for the app view.

Directives

Adding custom elements or attributes with the ng- prefix gives developers the freedom to compose an application in a unique way. All the new elements are added to the HTML code and they teach browsers show new elements and behavior.

Modules

You get a well-defined structure of the project that is split into manageable structures. A module looks like a container where you will find controllers, directives, filters and so on.

Testing

Unit or E2E testing is available for developers to make their way of building a new app easy and comfortable. Unit testing is used for defining bugs while the E2E testing is used for catching regressions, wrong components integration, etc.

What projects is Angular best for?

Here are a few examples where AngularJS is the most suitable technology to use. The list is not full but it gives a basic understanding of what kind of projects you can build up with AngularJS. If you plan to start a large-scale project, it’s good to make sure that the AngularJS development services are provided by experienced team players.

UGC websites

UGC stands for user-generated content. Take a look at Upwork or Freelancer.com that provide smooth and nonstop workflow. LinkedIn is a great example of a social network.

Video-streaming apps

Netflix, Youtube, and Vevo have impressive user interfaces and billions of visitors each year. Youtube is accessible from any device including the PS3 and it has about 1 billion users.

Business tools

One of the most well-known websites in this category is Localytics. Over 6,000 companies use it as business analytics and marketing platform.

Email services

Gmail by Google is a nice-performing example of a single page application where you don’t have to reload the page to see the new emails (content updates).

Travel portals

JetBlue is an example of a travel platform with over 35 million visitors each year. The data is changing all the time and users get reliable up-to-the-minute data about flights, reservations and so many other things.

How to hire AngularJS developers?

Building up a new web application starts with an idea, a detailed plan of action and hiring one or several AngularJS developers. Once you have a detailed plan of actions and a clear picture of how the app should look like and behave, you will know what kind of an expert you will need.

Hiring a pro developer from an outsourcing company will save your time from educating a new team player and providing comfortable working conditions. An outsourcing company will find the right person who will dive into a new project right on the first day of work. Cooperation with an AngularJS offshore development company is cost and time efficient.

Your new remote team member will have a well-equipped working place and all that is required for being motivated and inspired. The company takes care of all the payments like taxes, sick leaves and so on. You get a new team member that will become a part of your team that you can get in touch with at any time.

1. What is AngularJS?

AngularJS is an open-source client-side JavaScript framework that is used for developing dynamic and interactive single page applications that are compatible with mobile and desktop browsers. SPA means that the content updates within one single page.

2. How does AngularJS work?

AngularJS makes interactive user interfaces that do not require page reload for updating the content on a webpage. It extends the syntax of HTML with the help of directives to make a browser show specific elements.

3. Why do we use AngularJS?

Easy implementation of MVC helps us split the project into parts and saves developers from creating tons of code. Dependency injection makes AngularJS a great technology for the server-side part of the project. Auto-injected services let developers start a new project in a matter of moment. It comprises everything that a programmer may need for front-end development.

4. What is the meaning of AngularJS?

It’s a technology that is used for creating single page applications that mean updating or changing the content without reloading the page. AngularJS is a JS framework developed by Adam Abrons and Miško Hevery from Google team. This is one of the reasons for the framework popularity.

It’s an opinionated client-side solution for web applications that provides an easy and comprehensive approach for developers. It uses declarative programming for creating interactive user interfaces and uniting them with the server side.

5. What are AngularJS and Node.js?

Node.js is light and scalable runtime environment for real-time web applications. AngularJS is a front-end JS framework that is responsible for interaction with the users.

6. In which language is AngularJS written?

AngularJS is a framework that is written in JavaScript language.

7. What is AngularJS route when method?

Use when(path, route); to add a new route. For adding new routes, check the ngRoute module to be installed in advance. Use $routeProvider to configure existing routes.

8. Where is Angular route js?

ngRoute routing module is used by AngularJS for single page applications. The basis for the module is an URL. How does it work? A user requests a specific URL that is captured by the server and it renders the required view according to the routing rules.

Apache Cordova essentials

The major components of Apache Cordova are a WebView (for building a user interface), a Web App (for storing the code and information about the app), and Plugins (for accessing device API). There are two development paths for building a new app. The first is a CLI (cross-platform) workflow to create one codebase for several platforms. The second is a platform-centered workflow to get the access to adjusting low-level code.

Why use Apache Cordova?

Developing a new project requires a thorough choice of the technology to be used to make it cost and time efficient. Here are three major reasons to use Apache Cordova for a new app:

• If there’s a need to make the app compatible with other devices without the need to release it from start to finish one more time;
• If there’s a need to scale a project built for various app stores;
• If there’s a need to bind native app components with the WebView for accessing device API components.

What projects is Apache Cordova used for?

Here are successful projects built with Apache Cordova:

• Pacifica – for taking care of mental health;
• Sworkit – for exercising at home;
• JustWatch – for watching movies and shows;
• Clever Baby – for tracking growth and development of a baby;
• FanReact – for sharing experience with like-minded fans.

Hire Apache Cordova developers

The first stages of developing a new project are creating a detailed description and looking for the developers who will cope with the tasks. Finding a new member for your in-house team may become a good idea as you are aware of every stage of development. But a list of drawbacks (the need to train a newcomer, to organise a workplace, pay taxes, etc.) make this idea not so good. This has become the reason that companies hire freelance developers that are ready to jump into the project within just a few hours or days.

Apache Cordova development company

A company with a big number of pro Apache Cordova developers is a good choice if you want a reliable and secure deal. How can you check the proficiency of the team members? The easiest way is asking to explain why you should use this or another technology for building your project and to show you the projects developed in Apache Cordova.

Outsource Apache Cordova development company

Communication means wipe off the borders, so having your company team settled around the globe is not something awkward or unusual. Dealing with the offshore development company saves money as there’s no need to pay high rates for local experts and create a positive working place in the office. It’s also time efficient as you contact the company, describe the task and get as many pro developers as you need.

Apache Cordova development in Codemotion company

Building a cross-platform mobile application is an easy and fun task for Codemotion ninjas. We’re a fast-growing JavaScript development company with over 450 released projects and 10 years of experience. What makes us so special is the approach we use for working with clients. We stick to the Agile philosophy where we all turn into a single and united team aimed at creating a new application. Get a new app developed by a team of Apache Cordova ninjas with high performance and efficiency.

Angular essentials

AngularJS is a complex framework. In the standard delivery, it provides the following options:

• All you need to create CRUD applications like data-binding, basic template directives, form validation, routing, deep linking, component reuse, dependency injection, tools for interacting with a server, data sources.
• All you need for testing: means for unit testing, end-to-end testing, mock-and.
• A template for a typical application that includes a directory structure and test scripts.

Angular allows you to create single-page applications that are becoming popular. With the development of technology, more functionality is transferred to the browser and users solve a huge number of tasks without installing additional software on their computers. Single-page applications create the impression of working with standard programs. They reduce the load on the server and can provide a much richer interface for the end user.

Why use Angular?

Using the framework allows you to reduce development time. The main reason to choose any framework is the cost of the time of the programmer and with the development of computer capacities, we can use less labor-intensive solutions. An example of such a time saving is the ability to bind data. Angular gives this functionality by default right after the installation.

In order to get started, it’s enough to get just one file named angular.js It contains all the basic functionality that you need. All additional tools are divided into modules and can be added as needed.

What projects is Angular good for?

Angular is good for single-page applications. Here are a few examples of the projects that were built with Angular:

• Brilliant Earth at https://www.brilliantearth.com/
• TAP Air Portugal at https://www.flytap.com/en-us/
• Copa Airlines at https://www.copaair.com/en/web/us
• Microsoft Office Support at https://support.office.com/
• Google Pay at https://pay.google.com/send/home?authuser=0
• U.S. bank at https://www.usbank.com/index.html

Hire Angular Js developers

Developing a new app requires hiring a remote or in-house team. What makes the first option more efficient? Looking for a team of Angular developers that will work in your office requires a lot of time. You spend it on interviews and on letting people prepare for participating in a new project. Hiring freelance developers will definitely save your time and let you release the project much earlier.

Angular JS development company

You can hire an Angular development company that is located in any part of the world. If you see that it’s easy to communicate with a new team, explain your thoughts and details of the project, the cooperation will be easy and fun. You will get as many people for a new app as required. It can be a single developer or a whole team.

Outsource Angular JS development company

An outsource development company is a good choice if you want to use a powerful framework for building your apps with maximum cost and time efficiency. Discuss the goals, set the milestones for the project and just start your way.

Another approach to the architecture of different databases is microservices that can have their own database. They are better optimized for the tasks of this particular service. For example, the main repository can be on MySQL, Redis and Memcache for caching and Elastic Search or native Sphinx for searching. And we’ll need something like Kafka to transfer data to the analytics system that is often done on something like Hadoop.

If we are talking about the main operating repository, we will have two options. On the one hand, we can choose relational databases with SQL. On the other hand, we can have something non-relational and then look at the subspecies that are available in this case.

If we talk about the NoSQL data model, then there is a lot to choose from. The most common are either key value, or document, or wide column database. Examples: Memcache, MongoDB, Cassandra respectively.

Why do we compare MySQL and MongoDB? In fact, there are several reasons. If you look at Ranking databases, then you’ll see that MySQL is the most popular relational database and MongoDB is the most popular non-relational database. Therefore, it is reasonable to compare them.

MongoDB initially actively focused on MySQL users. Therefore, very often people have experience of using and choosing between these two technologies.

What to choose: MySQL and MongoDB

What are the advantages of these systems?

If we talk about MySQL, this is a well-known technology. It is clear that MySQL is used by large companies for more than 15 years. Since it uses the SQL standard, it is possible to easily migrate to other SQL databases if you want. There is a possibility of transactions. Complex queries, including analytics, are also supported.

From the point of view of MongoDB, here the advantage is that we have a flexible JSON-format of documents. For some tasks and for some developers it is more convenient than to suffer from the addition of columns in SQL-databases. Simple queries rarely make problems.

If you look at performance problems, they mostly arise when people write complex queries with JOIN in a heap of tables and GROUP BY. If there is no such functionality in the system, then it is more difficult to create a complex query.

MongoDB has simple scalability using the technology of shading. We usually solve complex queries on the side of the application. That is, if we need to do something like JOIN, we can go to select the data, then go to select the data from the links and then process them on the side of the application. For people who know the language of SQL, it looks somehow pathetic and unnatural. Development of the server applications is much easier than dealing with JOIN.

Development and application lifecycle

If we talk about applications where MongoDB is used and what they focus on is a very fast development. Because everything can be constantly changed, you do not need to constantly take care of the strict format of the document.

The second point is the data schema. Here you need to understand that the data always has a schema, the question is only where it is implemented. You can implement the data schema in your application because somehow you use this data. This scheme is implemented at the database level.

Very often if you have an application, only this application works with the data in the database. For example, we store data from this application in this database. The scheme at the application level works well. If we have the same data used by many applications, then it is very inconvenient and difficult to control.

What about the application lifetime? With MongoDB, it’s good to make applications that have a very limited life cycle. If we make an application that does not live long, for example, a site for running a movie or an olympiad. We lived several months after that, and this application is practically not used. If the application lives longer, then there is another question.

The data model depends very much on the application and experience of the team. If we compare them with each other, it is clear what we have. In MySQL, there’s a relational database. We can easily display links between tables using a relational database. By normalizing data, we can make the data changes happen atomically in one place. When the data is denormalized, we do not need to run and modify a bunch of documents with some changes.

Is it good or bad? The result is always a table. On the one hand, it’s easy, on the other hand, some data structures do not always fit well on the table, we may be uncomfortable with this work.

It’s all in theory. If we talk about the practical use of MySQL, we know that we often denormalize data, sometimes we use something similar for some applications: we store JSON, XML, or another structure in the application columns.

MongoDB has a data structure based on documents. The data of many web applications can be displayed very simply. Because if we store the structure as something like an associated application array, then it’s very easy for the developer to serialize it into a JSON document. Deploying this in the relational database on different labels is a tough task.

Example. We want to keep the contact list on the phone. It is clear that there’s data that is well placed in one relational table: Surname, Name, etc. But if you look at the phones or email addresses, then one person may have several. If such a file is stored in a good relational form, then it would be nice to store it in separate tables, then it’s all to collect JOIN, which is less convenient than storing it all in one collection where the hierarchical documents are located.

It should be said that this is all strictly relational theory as some databases support arrays. In MySQL, the JSON format is supported where you can put things like several email addresses.

The terms

It is interesting that between MySQL and MongoDB something is the same and different. For example, we are talking about databases in both cases, but what we call a table in a relational database is often called a non-relational collection. The fact that MySQL is a column, we have a field in MongoDB.

In terms of using JOIN, in MongoDB there is no such thing, it is a concept from a relational structure. We either create a built-in document that is close to the concept of denormalization, or we just save the document ID in a field, call it a link and then select the data we need.

Redux essentials

Elm and Flux came out a little bit earlier. They were used for Facebook. Developers faced some problems and difficulties with the scalability when using these tools. Redux became a magic wind with its unidirectional data flow. There’s one state that we can name as a central or root one. You can obtain one change at a time with a specific function.

Why use Redux?

Let’s think why you don’t actually need Redux for your project. If you have a simple application and you are not sure if you should use Redux or not, don’t rush. If a developer needs some specific tools for managing the app state and for testing it, you can consider using Redux as a major tool. It can be used with React.

What projects is Redux good for?

You can use this library together with Rect or any other tool. It’s good that we have a lot to say about Redux, but looking at real projects where it’s used will be much more helpful. Here are a few examples:

• https://mattermark.com/ – a powerful platform for intelligent business;
• https://www.here.com/en – for their tools;
• https://github.com/mozilla/payments-ui – Redux was used for the UI.

Hire React/Redux developers

Hiring a Redux developer is a tough task if you are looking for someone to become a part of your in-house team. You will require some time to pick up the candidates, conduct interviews and get ready to spend from one week to a few months educating people on new positions. Is there a more optimal way out?

One more variant is to hire freelance developers and cooperate with them remotely. You won’t have to spend so much time until they are ready to work on your new application. It can be an outsource company or individual Redux developers. You pick up the variant that fits you the most.

Redux JS development company

Working with a JavaScript development company provides you with a much more efficient workflow as you can always be sure that the qualification of every developer is proved. You can check the portfolio and find out real and true feedbacks from other company clients.

Outsource Redux JS development company

The most efficient application development in a matter of costs and time is when cooperating with a JavaScript outsourcing company. You save costs as you get the developers that are ready to jump into your project and you pay less for their work. You save time. Cooperating with an outsource Redux development team is a key to a much faster app release and an efficient workflow.

• Mobile apps with React Native;
• Safari, Opera, and Chrome extensions;
• MongoDB and similar databases;
• Scripts for LibreOffice, Unity, OpenOffice or Adobe CS;
• Google Desktop Gadgets, Yahoo! Widgets, Microsoft Gadgets or Apple Dashboard Widgets;
• And much more.

JavaScript has made a super great impact on the world of programming and it’s still becoming more and more popular. You can check the Github report regarding the languages that have the biggest number of open source contributions. This language has been developing and implementing new standards. Now we have ES2017. JavaScript has a high chance to keep its position in the future.

The stack

It has everything that you may need for developing a web application. MEAN stack is one of the most commonly used. It means the use of MongoDB, Express, AngularJS, and Node.js. But you are not limited to these technologies only. It’s good to be good at several stack versions. Let’s take a look at the most wanted combinations below.

Node.js + Express for the back-end

The goal of the technology is to make data transfer and implementation of all the required functions of the server side. Node.js is based on V8 JavaScript Engine. Node.js cannot use threads, but you can get the most out of creating child processes that are additionally supported by clusters.

Express is often used with Node.js as it’s a super great tool thanks to a big number of bridges between the OS and the database and so on.

React + Redux for the front-end

Facebook is a creator of React that acts out as a JavaScript library. You are free to use this technology for developing different visual interfaces for the web. If you take a look at Model-View-Controller pattern, you will find it in the V place. You can combine its features with Redux or even AngularJS.

React Native for the mobile

Use it for developing applications for mobile devices. You can use it for iOS and Android as well. There are some strong sides that we can even call as benefits like no need to recompile the code, reload the device all the time or hot reloading that adds a new part of the code but keeps the current state of the app. It’s not a good choice for battery and memory consuming applications.

MongoDB for the database

You will find JSON-like documents in the NoSQL system that we name as MongoDB. You can freely use JavaScript for queries. The format of the documents allows it perform all the processes fast. You can use it for several servers thanks to the sharding technology to level the load. MongoDB comprises replication systems for the automated fall-backs to replicas if any failure occurs.

Technology

How does JavaScript differ from other programming languages? Take a look below.

Prototypal inheritance

Let’s consider the model of inheritance for JavaScript as a prototypal inheritance. You can observe it since the ES2015 was established to add the class keyword to JavaScript. How does it look like in reality? An object can inherit from another object without any additional classes and it becomes a prototype of the former object. This is the major difference of this type of inheritance from the classical one where you will have so-called blueprints that stand for classes.

You won’t find extended classes in JavaScript as it has prototype chains instead of them. There’s no support for a multiple inheritances when we are talking about one level of the parent. A concatenative inheritance will help you use multiple inheritances with no pitfalls.

Functional code

It’s super great that you can use JavaScript for both Functional and Object-Oriented code. You can do whatever you want with the functions as if they were any other values thanks to their super role. You can do because there are specific concepts regarding lexical scopes and closures that preserve the state of the internal function even in the case when the outer scope or scopes finish.

Asynchronicity

You will not see anything related to the multi-threading when using JavaScript instead of other popular languages. You will have a chance to use Event-Loop and see how child processes and web workers provide you with a good performance. A good thing here is that you will not suffer from any performance problems as there won’t be any troubles with handling great numbers of threads. You will avoid IO-blocking that can lead to terrific consequences like ruining the UX completely.

Variadic functions

If you need to check the function or its components, you can take the exact number of them and see how they work, There’s no need to run the checkups for the parameters of the whole function. You won’t find this feature in most of the other languages.

To conclude

JavaScript is one of the most common languages for developing various applications around the globe. It will keep its position for a long time in the future. We advise you to start using it if you haven’t done this before.

How to conduct an interview with a JavaScript developer?

The popularity of responsive and full-featured applications has made JavaScript a handy tool for developing them. You get a great code that is delivered to you by a pro developer. So having such a person on your team will let you create a project that you wish. However, the process of choosing the right candidate for a position can be a tough task.

We’re giving you some practical tips on how to conduct an interview and define whether this very candidate fits the position. You can use the tips for hiring a front-end, back-end or full-stack developer. It’s not enough to turn symbols into lines of the code. You will need someone who can turn your ideas into some specific language syntax. What can you do within 20-30 minutes of the interview?

Define the level of expertise

The thing to focus on when interviewing is JavaScript chops and not some check-ups whether the candidate knows some basic coding. Take one general question and make every new question a bit more narrow and complicated until you see that the candidate cannot give you the answer. Don’t worry if the candidate has more experience in using other languages for the previous projects.

Find the drawbacks

Give the candidates some pieces of the code and ask them what they think about it if there are any drawbacks and how they would improve it. The candidates should be able to explain how the code will work, predict the outcome in case the errors are not fixed and so on.

Finish a simple task

The worst variant of performing this task is writing the code on a paper or on the board. However, there are some companies that require the candidates do this on the board. You can ask the candidates to perform this task during the interview or prepare it in advance if it may require too much time to finish.

View the portfolio

The last stage of the interview is analyzing the portfolio. It doesn’t have to be a static presentation of the projects. You will probably get the links to open source contributions or some past projects. Take a look at them and ask questions regarding the technologies used, some problems that the candidates had to solve and so on.

The finish line

If you are not aware of JavaScript, we recommend you to take someone who is good at it to be able to evaluate the answers of the candidates the right way. Communication matters, so watch how the candidates perceive what you say to them and how they react. If you feel that your conversation is easy to keep on and you get clear answers to all of your questions, you probably see the best candidate for the position of a JavaScript developer.
