React Native Introduction
Get started with React Native and learn how it enables cross-platform mobile development.
Learning Goals
The Core Concept
React Native is a popular framework created by Meta (Facebook) that allows you to build native mobile applications using JavaScript and React. Instead of writing separate code for iOS (in Swift/Objective-C) and Android (in Kotlin/Java), you can write one codebase that works on both platforms. It works by translating your React components into truly native mobile UI elements, giving your app a native look, feel, and performance.

Code & Implementation
import React from 'react';
import { View, Text, StyleSheet } from 'react-native';
export default function App() {
return (
<View style={styles.container}>
<Text style={styles.text}>Hello, React Native!</Text>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#f0f8ff',
},
text: {
fontSize: 24,
fontWeight: 'bold',
color: '#333',
},
});Expected Output
A mobile screen with a light blue background displaying 'Hello, React Native!' centered on the screen.
