How do async functions work in JavaScript?

Async functions in JavaScript allow you to write asynchronous code that looks synchronous. They return a promise.

Can you give me an example of an async function?

Sure! Here's a simple example:

async function fetchData() {
    let response = await fetch('https://api.example.com/data');
    let data = await response.json();
    return data;
}

What happens if I don't use await inside an async function?

If you don't use await, the function will return a promise immediately, and the code will continue executing without waiting for the promise to resolve.

Are there any limitations to using async functions?

Yes, async functions can only be used in environments that support Promises, and they can't be used as constructors.
