What are the differences between async/await and callbacks in Jest?

Can you explain the differences between using async/await and callbacks in Jest testing?

Sure! Async/await allows you to write asynchronous code that looks synchronous, making it easier to read and maintain. Callbacks, on the other hand, can lead to callback hell, making the code harder to follow.

What are the advantages of using async/await over callbacks?

The main advantages include improved readability, easier error handling with try/catch, and avoiding deeply nested structures that often occur with callbacks.

Can you give me an example of both in a Jest test?

Absolutely! For callbacks, you might use done() to signal completion. With async/await, you simply return a promise and use await to handle it, which makes the test cleaner.

Are there any scenarios where callbacks are preferred?

Yes, callbacks can be useful in scenarios where you need to handle events or when working with APIs that don't support promises.
