Developers may now test the Error Boundaries in React using a toggle error button introduced to the DevTools. Error boundary is triggered when we click the toggle error button on the 'Inner Component' component. The text An error was thrown is shown.
Error Boundaries are used to handle errors in class components. The most easy and effective way to handle problems that occur within your React components is to use error boundaries. If you use class component, you may construct an error boundary component by inserting the life cycle method componentDidCatch(error, info).
