What is the async/await pattern in Node.js?

The async/await pattern is a way to handle asynchronous operations in Node.js, making code easier to read and write.

Can you give me an example of how to use async/await?

Sure! Here's a simple example:

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 and waits for the response before proceeding.

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

Async/await makes your code cleaner and more readable by avoiding callback hell, and it allows for better error handling with try/catch.

Are there any limitations to using async/await?

Yes, async/await can only be used inside functions marked with the async keyword, and it may not work well with certain older Node.js versions.
