What is the difference between async and callbacks in JavaScript?

What is the difference between async and callbacks in JavaScript?

Async functions allow you to write asynchronous code that looks synchronous, making it easier to read and maintain.

Can you give me an example of using a callback?

Sure! A callback is a function passed as an argument to another function, which is then executed after some operation.

How does async/await improve code readability?

Async/await allows you to write asynchronous code in a more linear fashion, avoiding the 'callback hell' problem.

Are there any downsides to using async functions?

One downside is that async functions can be less performant than callbacks in some scenarios, especially if not used properly.
