Mobile React Native Skill

Core Principles

Expo managed first: Only eject when a native module is absolutely needed.

FlatList not ScrollView: For lists > 50 items — ScrollView renders all at once.

Reanimated on UI thread: Animations must not trigger the JS bridge.

MMKV for storage: 10x faster than AsyncStorage for non-sensitive data.

Zustand for client state: Redux is overkill for most mobile apps.
