What is callback hell and how can I avoid it?

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

Why is it considered a problem in programming?

It's problematic because it leads to code that is hard to follow, debug, and maintain, often resulting in errors.

What are some strategies to avoid callback hell?

You can use Promises, async/await syntax, or modularize your code to keep it clean and manageable.

Can you give me an example of using async/await?

Sure! Instead of nesting callbacks, you can write asynchronous code like this: async function fetchData() { const data = await getData(); console.log(data); }.
