How can I optimize my custom React hooks for better performance?

To optimize your custom hooks, consider using memoization with useMemo or useCallback to prevent unnecessary re-renders.

What are some common pitfalls to avoid when creating custom hooks?

Common pitfalls include not properly managing dependencies in effect hooks and causing excessive re-renders by returning new objects.

Can you give an example of a well-optimized custom hook?

Sure! A custom hook that fetches data can use useMemo to cache results and useEffect to manage the fetch lifecycle efficiently.

How do I test my custom hooks for performance?

You can use tools like React Profiler to measure the performance of your hooks and identify any bottlenecks.
