What's the best way to handle errors thrown due to undefined variables in a try...catch block?

Wrap the code that might throw an error in a `try...catch` block. Inside the `catch` block, you can log the error, display a user-friendly message, or attempt to recover from the error. Ensure the `catch` block handles the specific error type you're expecting (e.g., `TypeError` if accessing a property of `undefined`).
