An example of an AI chatbot conversation about error handling in React 18.
How can I handle errors in React 18?
In React 18, you can use error boundaries to catch JavaScript errors in your component tree. Would you like to know how to implement them?
Yes, please explain how to create an error boundary.
To create an error boundary, define a class component that implements either getDerivedStateFromError or componentDidCatch methods. This allows you to catch errors and display a fallback UI.
Can I use functional components for error boundaries?
Currently, error boundaries must be class components. However, you can use hooks to manage state and effects within your functional components.
What happens if an error occurs in a child component?
If an error occurs in a child component, the nearest error boundary will catch it and render the fallback UI you specified.
