What are some common mistakes when using the useEffect hook in React?

Some common mistakes include forgetting to add dependencies, causing infinite loops, and not cleaning up effects.

Can you explain what happens if I forget to add dependencies?

If you forget to add dependencies, the effect may run on every render, leading to performance issues or infinite loops.

What does it mean to clean up effects?

Cleaning up effects means returning a function from useEffect that will run when the component unmounts or before the effect runs again.

How can I avoid these mistakes?

To avoid mistakes, always specify dependencies, use the cleanup function, and test your effects thoroughly.
