What are JavaScript promises?

Can you explain what JavaScript promises are?

Sure! JavaScript promises are objects that represent the eventual completion or failure of an asynchronous operation.

How do promises differ from callbacks?

Promises provide a cleaner way to handle asynchronous operations compared to callbacks, avoiding callback hell.

Can you give me an example of how to use a promise?

Absolutely! Here's a simple example: let myPromise = new Promise((resolve, reject) => { ... }); You can use .then() to handle the resolved value.

What happens if a promise is rejected?

If a promise is rejected, you can handle the error using the .catch() method to execute error handling logic.
