What are the differences between Promises and Async/Await in Node.js?

What are the differences between Promises and Async/Await in Node.js?

Promises are objects that represent the eventual completion or failure of an asynchronous operation, while Async/Await is syntactic sugar built on top of Promises, making asynchronous code easier to read and write.

Can you give me an example of using Promises?

Sure! Here's a simple example:

const fetchData = () => {
    return new Promise((resolve, reject) => {
        setTimeout(() => {
            resolve('Data fetched!');
        }, 2000);
    });
};

fetchData().then(data => console.log(data));

And how would that look with Async/Await?

Using Async/Await, it would look like this:

const fetchData = async () => {
    return 'Data fetched!';
};

const getData = async () => {
    const data = await fetchData();
    console.log(data);
};

getData();

Which one should I use in my project?

It depends on your preference and the complexity of your code. Async/Await is generally easier to read and manage, especially with multiple asynchronous calls.
