  • Custom Hooks: Creating reusable logic.

  • React Context best practices.

• Performance Optimization:

  • Profiling and Debugging:

    • React DevTools Profiler: Identifying performance bottlenecks.

    • Using why-did-you-render for pinpointing unnecessary re-renders.

  • Memoization Techniques:

    • React.memo: Optimizing functional components.

    • useMemo and useCallback: Caching expensive computations and functions.
