React Native may default to TypeScript based on the latest templates. To create a project with JavaScript (`App.js`), follow these steps:
Solution 1: Create a JavaScript Project Directly
Run:
npx react-native init MyApp --template react-native-template-js
Solution 2: Convert TypeScript to JavaScript Manually
1. Rename `App.tsx` → `App.js`
2. Remove TypeScript Dependencies
npm uninstall typescript @types/react @types/react-native
3. Restart Metro Bundler
npm start --reset-cache
