### Expo Fundamentals

**Managed vs Bare Workflow**
- Managed workflow: Full Expo SDK, minimal native code
- Bare workflow: Full native code access with Expo modules
- **CNG (Continuous Native Generation)**: Best of both worlds
- Migration strategies between workflows

**Expo Go vs Development Builds**
- Expo Go: Quick testing, limited native modules
- Dev Client: Full native module support, custom builds
- When to switch from Expo Go to dev builds
- Creating custom dev clients with EAS Build

**Expo SDK & Modules**
- Core Expo modules (expo-camera, expo-location, expo-video, expo-audio)
- Third-party native module compatibility
- Module installation: `npx expo install <package>`
- Autolinking handles native setup automatically

### EAS Build (Cloud Builds)

**Build Profiles**
- Development builds: Fast iteration, dev client
- Preview builds: Internal testing, TestFlight/Internal Testing
- Production builds: App Store/Play Store submission
- Custom build prof
