What are some examples of async functions?

Async functions are functions that operate asynchronously, allowing for non-blocking execution. Examples include fetching data from an API or reading files.

Can you show me a code example of an async function?

Sure! Here's a simple example in JavaScript:

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

This function fetches data from an API asynchronously.

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

If you don't use 'await', the function will return a promise immediately, and the code following the asynchronous operation will execute without waiting for the promise to resolve.

Are there any drawbacks to using async functions?

Yes, while async functions simplify code, they can make error handling more complex and may lead to unhandled promise rejections if not managed properly.
