What are some common mistakes when using useEffect 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 not run when it should, leading to stale data or unexpected behavior.

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 infinite loops with useEffect?

To avoid infinite loops, ensure that your dependencies are correctly set and that your effect does not update state in a way that triggers itself.
