What is callback hell in programming?

Can you explain what callback hell is?

Callback hell refers to the situation in JavaScript where multiple nested callbacks make code difficult to read and maintain.

Why is it a problem in JavaScript?

It's problematic because it leads to deeply nested code, making it hard to follow the logic and increasing the chance of errors.

How can I avoid callback hell?

You can avoid it by using Promises or async/await syntax, which helps to flatten the structure of your code.

Can you give me an example of callback hell?

Sure! Imagine a series of asynchronous operations where each one depends on the previous one, leading to multiple levels of indentation.
