Why React Native?

React Native lets you build iOS and Android apps with one codebase. Write in JavaScript and React, deploy native apps. Used by Facebook, Instagram, and countless others.

Getting Started

npx create-expo-app MyApp
cd MyApp
npx expo start

Creating Components

import { View, Text, StyleSheet, TouchableOpacity } from 'react-native';

export default function Button({ title, onPress }) {
  return (
    
      {title}
    
  );
}

const styles = StyleSheet.create({
  button: { backgroundColor: '#3498db', padding: 15, borderRadius: 8 },
  text: { color: 'white', fontWeight: 'bold' }
});

Navigation

import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';

const Stack = createStackNavigator();

function App() {
  return (
    
      
        
        
      
    
  );
}

Conclusion

React Native offers the best of both worlds—React knowledge plus native performance. Expo simplifies the development process.
