What are the best practices for using useEffect in React?

When using useEffect, it's important to keep your dependencies array accurate to avoid unnecessary re-renders.

Can you explain how to manage cleanup in useEffect?

Absolutely! You can return a cleanup function from useEffect to handle any necessary cleanup when the component unmounts or before the effect runs again.

What should I include in the dependencies array?

Include all variables and props that are used inside the useEffect. This ensures the effect runs correctly when those values change.

Are there any performance considerations I should be aware of?

Yes, avoid using useEffect for heavy computations. Instead, consider using memoization or splitting effects to optimize performance.
