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

The best practices for using error boundaries in React include wrapping them around components that are likely to throw errors, using fallback UI to provide a better user experience, and logging errors for debugging purposes.

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

Sure! You can create an error boundary by defining a class component that implements the componentDidCatch lifecycle method and the getDerivedStateFromError static method.

What should I do if an error boundary catches an error?

When an error boundary catches an error, you should update the state to display a fallback UI and log the error for further investigation.

Are there any limitations to using error boundaries?

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

How can I test error boundaries in my application?

You can test error boundaries by simulating errors in your components and ensuring that the fallback UI is displayed correctly.
