When should I use callbacks vs promises?

Can you explain when to use callbacks instead of promises?

Callbacks are useful for simple asynchronous tasks, but they can lead to callback hell. Use promises for better readability.

What are the advantages of using promises over callbacks?

Promises provide a cleaner syntax with .then() and .catch(), making error handling easier and avoiding nested callbacks.

Are there situations where I should still use callbacks?

Yes, for very simple tasks or when working with older codebases that rely on callbacks, they can still be appropriate.

Can I mix callbacks and promises in my code?

Yes, you can mix them, but it's best to stick to one style for consistency and maintainability.
