React Native: What are React Native's performance optimization techniques?

Rendering optimizations:

1. Use React.memo for pure components
2. Avoid anonymous functions in props
3. Use useMemo/useCallback for expensive computations
4. Avoid inline styles for dynamic values

List optimizations:

• Use FlatList with getItemLayout
• Set removeClippedSubviews
• Use keyExtractor with stable IDs

Memory optimizations:

• Lazy load images and components
• Use image caching
• Clear unused data

Startup optimizations:

• Enable Hermes
• Use lazy module loading
• Defer non-critical initialization

Measurement:

• Profile with Flipper
• Monitor FPS
• Track memory usage
