What are some effective error handling techniques in Node.js?

In Node.js, you can use try-catch blocks, error-first callbacks, and promises with .catch() for error handling.

Can you explain how to use try-catch blocks in asynchronous code?

Sure! In asynchronous code, you can use try-catch with async/await. Wrap your await calls in a try block.

What about error-first callbacks? How do they work?

Error-first callbacks are functions that take an error as the first argument. If there's no error, the second argument contains the result.

Are there any best practices for error handling in Node.js?

Yes, always log errors, handle them gracefully, and avoid exposing sensitive information in error messages.
