Part 41 React Tutorial | Error boundaries in React | getDerivedStateFromError | componentDidCatch

Error boundaries are a feature in React that allow developers to catch and handle errors that occur during the rendering of a component tree. Normally, when an error is thrown in a component's render method, it will propagate up the component tree and potentially cause the entire application to crash. Error boundaries provide a way to handle these errors gracefully and display a fallback UI instead of crashing the entire application. To create an error boundary, you need to define a component that implements either or both of the following methods: static getDerivedStateFromError(error): This method is called when an error is thrown in a child component. It should return an object that will be used to update the component's state, allowing it to render a fallback UI. componentDidCatch(error, info): This method is called after an error is thrown in a child component. It is used to log the error or perform other side effects
