What is async/await in Node.js?

Async/await is a syntax in JavaScript that allows you to work with asynchronous code more easily. It makes your code look synchronous, which can be easier to read and maintain.

How does it differ from promises?

While promises represent a value that may be available now or in the future, async/await is built on top of promises. It allows you to write asynchronous code in a more synchronous style, making it easier to handle errors and manage flow.

Can you give me an example?

Sure! Here's a simple example:

async function fetchData() {
    try {
        const response = await fetch('https://api.example.com/data');
        const data = await response.json();
        console.log(data);
    } catch (error) {
        console.error('Error fetching data:', error);
    }
}

This function fetches data from an API and handles errors gracefully.

What are the benefits of using async/await?

The main benefits include improved readability, easier error handling, and a more straightforward way to write asynchronous code without chaining multiple .then() calls.
