How can I optimize performance in my React app using hooks?

You can optimize performance by using useMemo and useCallback to memoize values and functions, reducing unnecessary re-renders.

Can you explain how useMemo works?

Sure! useMemo returns a memoized value. It only recalculates the value when one of its dependencies changes, which helps avoid expensive calculations on every render.

What about useCallback? How is it different?

useCallback is similar but is used to memoize functions. It returns a memoized version of the callback that only changes if one of the dependencies has changed.

Are there any other hooks that can help with performance?

Yes! You can also use React.lazy and Suspense for code splitting, which can improve load times by splitting your app into smaller chunks.
