What are the best practices for using callbacks in programming?

When using callbacks, it's important to keep them simple and avoid deep nesting. Also, consider using named functions instead of anonymous ones for better readability.

Can you explain why deep nesting is a problem?

Deep nesting can lead to callback hell, making your code hard to read and maintain. It can also increase the risk of errors.

What are some alternatives to callbacks?

Alternatives include Promises and async/await syntax, which can help manage asynchronous operations more cleanly.

How do I convert a callback function to a Promise?

You can wrap the callback in a Promise constructor, resolving it in the callback's success case and rejecting it in the error case.
