# Expo React Native Performance Best Practices

Comprehensive performance optimization guide for Expo React Native applications. Contains 42 rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.

## When to Apply

Reference these guidelines when:
- Writing new React Native components or screens
- Implementing lists with FlatList or FlashList
- Adding animations or transitions
- Optimizing images and asset loading
- Reviewing code for performance issues
