What is React Native?

React Native is a JavaScript Framework for developing mobile apps for iOS and androids. It is an open-source UI software framework and was created by Meta Platforms Inc. It enables us to use the React framework along with native platform capabilities. This framework able you to create an application for various platforms by using the same codebase. It also works like React but it allows you to develop apps for both mobile and desktop.

React − It is a framework for building mobile apps as well as web apps using JavaScript.

Native − we can use native components controlled by JavaScript.

Platforms − React Native supports Android and IOS platform.

History of React native:

React Native was first released by Facebook in 2015. In just a few years, it is now one of the top solutions used for mobile development. React Native development is used by many of the world’s leading mobile apps, including Instagram, Facebook,and Skype.

Basic program using React Native:

A Hello, World program in React Native looks like this:

import { AppRegistry, Text } from ‘react-native’;

import * as React from ‘react’;

const HelloWorldApp = () => {

return <Text>Hello world!</Text>;

}

export default HelloWorldApp;

AppRegistry.registerComponent(‘HelloWorld’, () => HelloWorldApp);

React vs React Native: 

React (also known as ReactJS) is a JavaScript library used for building the frontend of a website.  It was also developed by the Facebook team

React Native,which is developed by React is a set of UI components which allows developers to quickly compile and launch iOS and Android apps.

In React we uses HTML and CSS, whereas in React Native we use native mobile user interface elements. Both React and React Native is a mix of JavaScript and a special markup language, JSX. However, the syntax used are different to render elements in JSX components differs between React and React Native.

Advantages of using React Native: 

We live in the era of Digital world; thousands of mobile applications are launched every day and total number of mobile apps will exceed 300 million by 2022 and this proves that demand for mobile apps are increasing day by day and dependency on smartphones are in growth.

Some of the benefits of React Native development for which React is in demand are given below:

1. Amazing mobile performance:

By the use of React Native one can easily develop complex mobile application. Even Facebook uses React Native on more than 800+ screens. When first React Native was introduced many companies was not ready to switch to native development to the cross platform due to lots of difference in performance. But as time passed React Native was matured, it becomes the most effective.

 2. Reusability:

It has been the most desired thing for the developers, as it brings a considerable difference in the cost of the application/ software, reducing the amount of time and resources required in the development process.

Due to the cross-platform nature of React Native it allows the developers to reuse the components interchangeably within both the platforms that are Android and iOS. So, once if you have written a JavaScript code for your application for one platform, you can directly compile and reuse it for the other, eventually reducing the development cost and time.

3.Cost & time efficient:

Due to the reusability feature of React Native app development company, it saves a lot of time and money.Currently, the cost associated with creating an app can be reduced by 30-35% when choosing React Native

4. Easily Maintainable:

It allows developers to make changes in application remotely without even disturbing users application usage. Normally, to update an application we need to make changes in the code of the applications and version to the app store and have to wait for the approval from apps store to implement. It also helps users even because no need to download the updated version. Instead of that Code Push Plugin is used and this saves the cost for versions maintenance.

5. Large Community:

According to research, React Native has a very large community and it is the most used cross- platform framework. It has more than 95K stars on GitHub which gives full advantage to the developers and their contribution help developers to learn new things and fix any issue while developing.

6. Instantly View Changes: 

In React Native we get feature of “Live Refresh/ Reloading” or “hot reloading” which allows developers to immediately view the changes made by them in real time. In live preview window developers can simultaneously view the changes .This feature help in getting real time feedback.
