What is the difference between error boundaries and try-catch in React?

What is the difference between error boundaries and try-catch in React?

Error boundaries are React components that catch JavaScript errors in their child component tree, while try-catch is a JavaScript construct used to handle exceptions in any code block.

Can you give me an example of how to use 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 happens if an error occurs outside of a React component?

If an error occurs outside of a React component, it won't be caught by error boundaries. You would need to use try-catch to handle those errors.

Are there any performance implications of using error boundaries?

Error boundaries can have a slight performance overhead, but they are essential for gracefully handling errors in a React application.
