How do callbacks, promises, and async/await compare in JavaScript?

How do callbacks, promises, and async/await compare in JavaScript?

Callbacks are functions passed as arguments to other functions, executed after a task completes. They can lead to 'callback hell' if nested.

What are promises then?

Promises are objects that represent the eventual completion (or failure) of an asynchronous operation. They allow chaining with .then() and .catch() methods.

And what about async/await?

Async/await is syntactic sugar over promises, making asynchronous code look synchronous. It simplifies the code and improves readability.

Which one should I use in my project?

It depends on your needs. For simple tasks, callbacks might suffice. For more complex flows, promises or async/await are recommended for better readability.
