To optimize React Native app performance and fix scrolling jank, apply specific list optimizations and UI thread operations to reduce excessive re-renders and improve FPS. This ensures a smooth, responsive user experience during interactions.

The best way to reduce React Native bundle size is to analyze the JavaScript bundle to identify and remove optimization opportunities. This process targets large bundle issues that slow down initial load times and degrade application responsiveness.

To find and fix memory leaks in a React Native application, you must use performance profiling tools to monitor memory usage and apply targeted optimization strategies. This resolves underlying memory issues that cause app instability.

You can improve TTI and FPS in React Native by applying JavaScript and native module efficiency optimizations alongside build process improvements. Measuring these metrics first helps identify specific UI rendering bottlenecks to address.

To start profiling React Native rendering issues, you need an understanding of performance profiling tools and best practices for native development environments. This prerequisite knowledge is required to accurately measure FPS and diagnose UI thread problems.
