What is async/await in JavaScript?

Async/await is a syntax for working with asynchronous code in JavaScript, making it easier to read and write.

How does it differ from promises?

While promises represent a value that may be available now or in the future, async/await allows you to write asynchronous code that looks synchronous.

Can you give me an 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;
}

What happens if an error occurs?

You can handle errors using try/catch blocks around your await calls, which makes error handling straightforward.
