React Native

 ( Cross-platform Software ) 

React Native is an open-source User interface software framework developed by Meta Platforms (formerly Facebook Inc.). It is used to develop applications for Android, Android TV, iOS, macOS, tvOS, Website, Windows and UWP by enabling developers to use the React framework along with native platform capabilities. It is used to develop Android and iOS applications at Facebook, Microsoft, and Shopify. It is also being used to develop virtual reality applications at Oculus.

Inside Facebook, Jordan Walke developed software that generated User interface elements for iOS from a background JavaScript thread, which became the basis for the React web framework. They decided to organize an internal hackathon to perfect this prototype in order to be able to build Mobile app with this technology.

In 2015, after months of development, Facebook released the first version for the React JavaScript Configuration. During a technical talk, Christopher Chedeau explained that Facebook was already using React Native in production for its Group App and its Ads Manager App.

React components wrap existing native code and interact with native APIs via React's declarative UI paradigm and JavaScript. TypeScript is often used over JavaScript in modern React Native applications due to its increased type safety.

While React Native styling has a similar syntax to CSS, it does not use HTML or CSS. Instead, messages from the JavaScript thread are used to manipulate native views. Using plugins, Tailwind CSS can also be used with React Native.

React Native is also available for both Windows and macOS, which is currently maintained by Microsoft.

import { AppRegistry, Text, View, Button } from 'react-native'; import React from 'react';

const HelloWorldApp = () => {

 const [count, setCount] = React.useState(0);
     

 const incrementCount = () => {
   setCount((prevCount) => prevCount + 1);
 };
     

 return (
   
     Hello world!
     {count}
     
   
 );
     

export default HelloWorldApp;

AppRegistry.registerComponent('HelloWorld', () => HelloWorldApp);

   title: string; // Required prop
   baseNumber?: number; // Optional prop
     

   const [count, setCount] = React.useState(baseNumber || 0);
     

   const incrementCount = (): void => setCount((prevCount) => prevCount + 1);
     

   return (
       
           {count}
           
       
   );
