Lesson 5: Running Your First React Native App

Introduction: Running your app allows you to see your code in action.

Steps:

1. Start the Expo Development Server: Run expo start.
2. Open the App in Expo Go:
   • Scan the QR code with Expo Go on your device.
   • Alternatively, use an Android or iOS emulator.
3. Modify the App:
   • Open App.js in your code editor.
   • Change the text to:
     import React from 'react';
     import { Text, View } from 'react-native';

     const App = () => {
     return (
     <View>
     <Text>Hello, React Native World!</Text>
     </View>
     );
     };

     export default App;


   • Save and see the changes instantly.

Conclusion: Running your first React Native app is an exciting step. You can now see how changes in your code are reflected in the app in real-time.
