What are async functions in JavaScript?

What are async functions in JavaScript?

Async functions are a way to work with asynchronous code in JavaScript, allowing you to write cleaner and more readable code.

How do I define an async function?

You define an async function using the async keyword before the function declaration. For example: async function myFunction() { ... }.

Can you explain how await works inside async functions?

The await keyword can only be used inside async functions. It pauses the execution of the function until the Promise is resolved.

What happens if I don't use await with a Promise?

If you don't use await, the Promise will still execute, but the function won't wait for it to complete, leading to potential timing issues.

Are there any limitations to using async functions?

Yes, async functions can only return Promises, and error handling can be a bit different compared to synchronous code.
