How can I implement custom error handling in my React app?

You can implement custom error handling in React by using error boundaries. They allow you to catch JavaScript errors in your component tree.

What are error boundaries and how do I create one?

Error boundaries are React components that catch errors during rendering. You can create one by defining a class component with a static method called getDerivedStateFromError.

Can I use hooks for error handling?

Yes, you can use hooks like useEffect to handle errors in functional components, but for catching rendering errors, error boundaries are still necessary.

What should I do when an error occurs?

You can display a fallback UI, log the error to an error reporting service, or provide a retry option to the user.
