What is an error boundary in React?
An error boundary is a React component that catches JavaScript errors in its child component tree, logging those errors and displaying a fallback UI.
How do I implement an error boundary?
You can implement an error boundary by creating a class component that defines either static getDerivedStateFromError() or componentDidCatch() methods.
Can error boundaries catch errors in asynchronous code?
No, error boundaries do not catch errors in asynchronous code, such as those in setTimeout or Promises.
What should I display in the fallback UI?
In the fallback UI, you can display a user-friendly message, a retry button, or any other UI that helps the user understand something went wrong.
