What are some common pitfalls when using hooks in React?

Some common pitfalls include forgetting to include dependencies in the dependency array, using hooks conditionally, and not understanding the rules of hooks.

Can you explain why using hooks conditionally is a problem?

Using hooks conditionally can lead to unpredictable behavior because React relies on the order of hooks calls. If the order changes, it can break the component's state.

What happens if I forget to add a dependency in the dependency array?

If you forget to add a dependency, the effect may not run when it should, leading to stale data or unexpected behavior in your component.

How can I avoid these pitfalls?

To avoid these pitfalls, always follow the rules of hooks, use ESLint with the hooks plugin, and thoroughly test your components.
