What are the best practices for using callback functions in programming?

When using callback functions, it's important to keep them simple and focused. Avoid deep nesting to enhance readability.

Deep nesting can make code harder to read and maintain. It can also lead to callback hell, making debugging difficult.

What are some alternatives to using callback functions?

You can use Promises or async/await syntax as alternatives, which can help avoid callback hell and improve code clarity.

Are there any performance concerns with using callbacks?

Generally, callbacks are efficient, but excessive use can lead to performance issues if not managed properly, especially in large applications.
