What are the best practices for using error boundaries in React?

Error boundaries are crucial for handling errors in React components. Best practices include wrapping components that may throw errors, using static methods like getDerivedStateFromError, and logging errors for debugging.

Can you give an example of how to implement an error boundary?

Sure! You can create an ErrorBoundary component that implements componentDidCatch and getDerivedStateFromError. Then, wrap your components with this ErrorBoundary.

What should I do if an error occurs in a nested component?

You can wrap the nested component with its own ErrorBoundary. This way, you can handle errors at different levels of your component tree.

Are there any limitations to using error boundaries?

Yes, error boundaries do not catch errors in event handlers, asynchronous code, or errors thrown in the ErrorBoundary itself.
