React Native

What is React Native and what does it do?

React Native is an open source UI framework for building mobile applications introduced by Facebook. With the help of React Native and JavaScript language, we can create applications for Android, iOS, Web and even UWP (a platform for building applications under Windows, Windows Mobile, Xbox and other Microsoft products). In this article, we look at what React Native is and what its benefits are.

world of Attractive JavaScript

JavaScript is a popular programming language. With the power and flexibility of JavaScript, almost anything can be done with it. For example, web page animation is done with the help of JavaScript and libraries such as Jquery, etc.

JavaScript on the server side has an executable environment called Node.js, and frameworks like Express.js help the programmer work on the server side with JavaScript as well. Web games can be created with JavaScript and HTML. React Native and JavaScript can also be used to build mobile applications for various platforms.

What is React Native?

Based on another popular Facebook service, React, which is used in user interface design (UI). But unlike React, which focuses on the browser, React Native is used to build mobile apps.

In other words, React Native has made it possible for web developers to build applications that behave exactly like programs written in Native. Because so many programmers love and use JavaScript, the React Native experience can be enjoyable.

React Native programs such as React are written in JavaScript and JSX. Then you can output these codes for Android and iOS. Note that the program you write with React Native does not have Webview mode and produces real UI components. In fact, your app is no different from other mobile apps written in Native language.

Why should we use React Native?

As you know, Android and iOS have a large share of the mobile market. The official language for building apps for Android is Java (although it has been a while since Kathleen has been added) as well as iOS apps using Swift. Programs written with Java and Swift are called native. You may be wondering why we have to go to frameworks and interfaces like React Native, despite native languages. Here are the benefits of using React Native:

  • Write once, use several places

Usually, those who start mobile programming choose between Android and iOS and become experts in that field. There are fewer Android developers who can build apps for iPhones. In this case, the programmer must learn the native language of that operating system to program in a particular operating system. This exclusivity can be a little annoying. But React Native allows you to write mobile applications in JavaScript, and React converts this code into Native language and gives you Android and iOS output.

  • Ability to use Native languages ​​next to React

During the project you may need to write some parts of the program in Native Java and Swift languages. React allows you to use these languages ​​alongside JavaScript whenever you like. You can also add React Native to your previous projects, and you don’t have to go all the way with React from the beginning.

  • Save time and money

Since React written apps give you different outputs such as Android, iOS and the web.Companies no longer need to hire multiple developers for different platforms. This React Native advantage greatly reduces costs and speeds up the application development process. All businesses want to keep costs down as much as possible, especially startups with limited financial resources. You can save time and money by using React Native.

  • Strong support by a large team of programmers

Facebook introduced this framework in 2015 and continues to support it to this day. React Native is an Open Source and its code is available in GateHub. In 2018, React Native was the second rank in the GateHub as the second largest contributor among all Repositories. There are also many forums and programmers in the world that you can count on if you have a problem.

Which brands use React Native?

There are many benefits to using this framework, and smart companies around the world have discovered these benefits. Some of the most popular services that we use every day have relied on it and have used this framework in various parts of their service. Here are some of the most popular brands that use it:

  • Facebook

Can a manufacturer of a product not use that product? Facebook introduced It as a solution to some of its problems within the organization. Then show the power of this framework in Facebook application and Facebook ad management application. He also used this framework in his statistical service called Facebook Analytics.

  • Instagram

The social network broke the record of 1 billion users in the world and is the most popular service in the field of image and video sharing. Changing the platform and moving the entire app to it, was a big challenge for Instagram developers. But Instagram accepted the risk and saw the result. After this change, maintaining both Android and iOS versions of this application became much easier.

  • Discord

If you love computer games, you have probably heard of Discord. A great social network for chatting between players that has many different capabilities. The interesting thing to know about Discord is that the Android and iOS versions of this program have 98% common code and Discord is a successful implementation example of RN.

  • SoundCloud

SoundCloud is one of the most popular music and audio file sharing services with many users. The company had a large number of iOS developers, which made the difference between the Android output and the iOS output of the app a little bigger. After conducting various experiments, they concluded that was an ideal option and designed their service entirely under this platform.


In this article, we explored what is it and what the benefits are of using it. It allows us to design the user interface of mobile applications using the JavaScript language. No need to be fluent in Native mobile programming languages ​​like Java or Swift. In fact, this framework is not going to replace native or native languages, but it is a good solution for mobile programmers and JavaScript enthusiasts to use this lovely language for mobile applications.
