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

Can you explain the difference between error boundaries and try-catch in React?

Sure! 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.

When should I use error boundaries instead of try-catch?

Use error boundaries for catching errors in the rendering phase of React components, while try-catch is better for synchronous code execution.

Can error boundaries catch errors in asynchronous code?

No, error boundaries only catch errors during rendering, lifecycle methods, and constructors of the whole tree below them. For async code, you should use try-catch.

What happens if an error occurs outside of an error boundary?

If an error occurs outside of an error boundary, it will crash the entire application unless handled by a global error handler.
