What is React Native? Advantages, Features & Importance

React Native for Mobile App Development

Mobile Apps are now the most hot commodities that business has to offer to its customers. No matter how big or small your enterprise is, a mobile app puts you on the map in the market. An intuitive, engaging, user & platform-friendly is what forms an ideal Mobile App. REACT Native Development, is becoming a key player when it comes to developing mobile apps.

What it is?

React Native is a JavaScript framework for writing real, natively rendering mobile apps for iOS and Android. It’s based on React, Facebook’s JavaScript library for building user interfaces, specifically targeting mobile platforms instead of the browser. It was invented by Facebook, in 2015, and has been a popular choice among developers.

By using React Native, web developers write mobile applications that look and feel ‘native’. By that, we mean requiring minimal computational overhead and extra components. Additionally, React Native makes it easy to simultaneously develop code for both Android and iOS.React Native applications are built on the Javascript framework that is based on-

  • JSX (extension to JavaScript)
  • ES6 based syntax, state, and props.

Thousands of applications are using React Native. Right from established Fortune 500 companies to hot new startups. 

Eager to know what it can achieve?

Well, here are some examples-

  • Facebook
  • Instagram
  • Tesla
  • Airbnb
  • Bloomberg
  • Pinterest
  • Skype
  • Uber
  • Wix.com

Advantages of React Native

React Native Advantages
  1. Web developers can easily enhance his/her skills and create React apps. 
  2. It helps in formulating cross-platform mobile apps.
  3. With RN, it’s time and cost-effective to build mobile apps on multiple platforms.
  4. It is a mobile framework that organizes app components for native mobile applications in JavaScript.
  5. It lends speed and readiness to the mobile apps with receptivity and a great native app-based UX.
  6. Hot reloading, a feature in RN, keeps the app running in the background while enabling the developer to implement new versions and tweak the UI.


React Native Features
1. Write Once and Use Everywhere

The code that is written in React Native works on almost every mobile platform. Including IOS, Android, Windows, etc. No need to write code in Swift for IOS, java for android or C# for windows. 

2. Programming Language

A framework using a popular programming language is one of the important factors influencing developer’s choice. 
React Native uses Javascript, and that what makes it more developer-friendly. Javascript is the most widely used programming languages. It is one of the three core technologies of the World Wide Web(WWW), HTML and CSS.

3. UI Focussed

The whole focus of React Native is solely on UI design. It is exceedingly responsive and its rendering techniques are by far the best.

4. Development Time & Cost Effectiveness

It requires less monetary resources and the whole development cycle of an application is of a shorter period. It simply boosts overall productivity. 

5. Mobile Environment Performance

The maximum number of the native applications are CPU oriented. On the contrary, applications built using React Native are GPU (Graphics Processing Unit)-oriented. This guarantees better performance compared to CPU-oriented applications.

6. NPM for Installation

The installation process is always trouble, especially for beginners. However, React Native uses Node Package Manager or NPM for installation and it is reasonably easy to use and learn.

7. Support for Third-Party Libraries

RN Framework effortlessly hooks with native modules and there are numerous third-party libraries available.

8. Smaller Teams

Unlike Native development, which requires two separate teams for Android and iOS, React Native, you will mostly need a JavaScript developer, who can write the code for both platforms. 

Thus requiring smaller teams that are easier to manage, achieving results instantly.

Importance of REACT Native Framework 

-Enables you to render UI for both iOS and Android platforms.

-An open-source framework, which shortly, could be compatible with other platforms like Windows or tvOS.

-Its components have counterpart rights, so the components can be reused for building both Android and iOS applications.

-It is a great pick for those developers who have expertise in JavaScript as there is no need to learn Android specific Java or iOS’s Swift.

-Since it is a UI focused, it makes the apps load quickly and gives a smoother feel.


REACT Native Framework is undoubtedly the number one choice for almost every app development company to develop mobile apps. An RN expert developer not only attains the agility and ease while developing the REACT Native apps but also experiences high efficiency and low cost & workload throughout the process.   Hence, many giant corporations in the world rely on this Framework to produce exciting apps that we use daily.
