What are the limitations of error boundaries?

What are the limitations of error boundaries in React?

Error boundaries can only catch errors in the components they wrap. They won't catch errors in event handlers, asynchronous code, or errors thrown in the error boundary itself.

Can error boundaries catch errors in class components?

Yes, error boundaries can catch errors in class components, but they won't catch errors in functional components unless those components are wrapped in an error boundary.

What happens if an error boundary itself throws an error?

If an error boundary throws an error, it won't be caught by itself. Instead, it will propagate up to the nearest error boundary or crash the app.

Are there any best practices for using error boundaries?

Yes, it's best to use error boundaries at a high level in your component tree to catch errors from multiple components, and to provide fallback UI to enhance user experience.
