What are the best practices for functional components in React?

Some best practices include using hooks for state and lifecycle management, keeping components small and focused, and using prop types for type checking.

Can you explain how to use hooks effectively?

Sure! Hooks like useState and useEffect allow you to manage state and side effects in functional components without needing class components.

What about performance optimization?

For performance, consider using React.memo to prevent unnecessary re-renders and useCallback to memoize functions.

Are there any common pitfalls to avoid?

Yes, avoid using hooks conditionally and ensure that dependencies in useEffect are correctly specified to prevent bugs.
