To fix React Native jank and frame drops, optimize JavaScript thread blocking, reduce bridge overhead, and apply FlashList for efficient list rendering. Profiling helps identify specific bottlenecks causing UI stutter.

The best way to reduce React Native bundle size involves analyzing the bundle structure and applying specific optimization strategies. This includes minimizing import bloat and optimizing Hermes engine usage for a smaller footprint.

Optimize React Native startup time and TTI by configuring the Hermes engine, reducing initial JavaScript thread blocking, and streamlining native module initialization. Profiling components helps isolate slow-loading dependencies.

Your React Native app feels sluggish during scrolling due to UI rendering bottlenecks and excessive re-renders. Replacing standard lists with FlashList and optimizing animation overhead resolves these performance issues.

Yes, you can use Hermes optimization to improve React Native performance. Hermes reduces memory leaks, decreases bundle size, and minimizes JavaScript thread blocking, directly enhancing app FPS and startup times.

Profile memory leaks and re-renders in React Native by using built-in debugging commands and performance guidelines. Structured profiling isolates bridge overhead and native module inefficiencies to prevent frame drops.
