Identify React performance bottlenecks by profiling with React DevTools Profiler to locate expensive render paths, then apply memoization, code splitting, or virtualization to optimize rendering and validate the improvements through measurement.

The best way to improve Core Web Vitals and reduce bundle size is implementing code splitting for large datasets and heavy components, systematically measuring the production performance regressions to ensure the optimizations yield tangible results.

Resolve memory leaks by profiling diagnostics to detect abnormal memory usage patterns, applying targeted memory management strategies and concrete fixes, then validating through measurement-guided checks to ensure stable memory consumption.

Yes, this approach works across development to production contexts, applying profiling with DevTools during development and validating actionable optimizations against production performance regressions to ensure real-world improvements.

Use virtualization for rendering slow lists and large datasets, and apply memoization to prevent unnecessary re-renders of heavy components, prioritizing these actionable optimizations based on profiling diagnostics that identify expensive render paths.
