What is the difference between async and promises in JavaScript?

Async functions are a way to work with promises more easily. They allow you to write asynchronous code that looks synchronous.

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

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;
}

How do promises work in JavaScript?

Promises represent a value that may be available now, or in the future, or never. They have three states: pending, fulfilled, and rejected.

When should I use async functions instead of promises?

Use async functions when you want to write cleaner, more readable code that handles asynchronous operations without chaining multiple .then() calls.
