What is the difference between callbacks and promises?

Can you explain the difference between callbacks and promises in JavaScript?

Sure! Callbacks are functions passed as arguments to other functions, executed after a task is completed. Promises, on the other hand, are objects that represent the eventual completion (or failure) of an asynchronous operation and its resulting value.

Can you give me an example of each?

Of course! For a callback, you might have a function that takes another function as an argument and calls it after a delay. For a promise, you would create a promise that resolves or rejects based on an asynchronous operation, like fetching data from an API.

Which one is better to use?

Promises are generally preferred over callbacks because they provide better error handling and can be chained, making the code cleaner and easier to read.
