What are the best practices for using hooks in React?

Some best practices include using hooks at the top level of your component, avoiding conditional hooks, and grouping related state.

Can you explain why hooks should not be called conditionally?

Calling hooks conditionally can lead to inconsistent behavior and bugs, as React relies on the order of hooks to manage state.

What about using multiple state variables with useState?

It's often better to use multiple state variables for clarity, but you can also use a single state object if it makes sense for your component.

Are there any performance considerations I should be aware of?

Yes, be mindful of unnecessary re-renders. Use memoization techniques like useMemo and useCallback to optimize performance.

Can you give an example of a custom hook?

Sure! A custom hook could be a useFetch hook that handles data fetching and loading states for you.
