What are promises and async/await in JavaScript?

Can you explain what promises are in JavaScript?

Sure! A promise in JavaScript is an object that represents the eventual completion or failure of an asynchronous operation.

How do async and await work with promises?

Async and await are syntactic sugar built on top of promises. The 'async' keyword makes a function return a promise, and 'await' pauses the execution until the promise is resolved.

Can you give me an example of using async/await?

Of course! Here's a simple example:

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