React Native is a JavaScript framework for writing real, natively rendering mobile applications for iOS and Android. It is based on React, Facebook’s JavaScript library for building user interfaces, but instead of targeting the browser, it targets mobile platforms.
For example, here is a simple “Hello World” React Native app:
import React from ‘react’;
import { Text, View } from ‘react-native’;
const App = () => {
return (
Hello World!
);
};
export default App;
