What are some examples of async functions in JavaScript?

Async functions in JavaScript allow you to write asynchronous code in a more readable way. For example, you can use the async keyword before a function to make it asynchronous.

Can you show me a simple example?

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;
}

This function fetches data from an API and returns it.

What does the await keyword do?

The await keyword pauses the execution of the async function until the Promise is resolved, making it easier to work with asynchronous code.

Are there any common mistakes to avoid with async functions?

Yes, a common mistake is forgetting to use await when calling an async function, which can lead to unexpected results.
