React Native प्रोजेक्ट की संरचना कैसी होती है?

my-app/
  App.js / App.tsx       → the root component (app entry point)
  src/ (or app/)         → your JS/TS code (components, screens, etc.) — organize here
  package.json           → dependencies and scripts (npm/yarn) — like any JS project
  node_modules/          → installed npm dependencies
  ios/                   → the native iOS project (Xcode) — for bare RN
  android/               → the native Android project (Gradle) — for bare RN
  index.js               → registers the root component
  app.json / app.config  → app config (name, icon) — especially in Expo
  (Expo projects hide ios/android; managed by Expo)
