Understanding React Native's internal workings and optimizing code is crucial for building high-performing mobile apps.
Key strategies include keeping lists lean by using FlatList or SectionList, avoiding unnecessary renders with React.memo and useCallback, optimizing asset usage for better performance, reducing JS bundle load by auditing imports, and keeping the UI thread free.
Regularly applying techniques like compressing images, lazy loading, and reducing bundle size can help maintain smooth and efficient apps.
Remember, performance optimization is an ongoing process that requires monitoring, tweaking, and iterating to ensure the best user experience.
