How does this skill help with FlatList performance?

It provides specific configuration patterns like getItemLayout, initialNumToRender, and memoized render items to ensure smooth scrolling even with large, complex datasets.

How do I identify performance bottlenecks using this skill?

The skill includes implementation patterns for the React DevTools Profiler and Performance Monitor to help you measure component render times and identify slow operations.

Does it support image optimization libraries?

Absolutely. It covers best practices for using react-native-fast-image for better caching and priority management, as well as native image prefetching techniques.

Can this skill help reduce my app's bundle size?

Yes, it includes guidance on enabling the Hermes engine, implementing code splitting with React.lazy, and using ProGuard for Android to minimize the final build size.
