What are the differences between async.js and Bluebird?

Async.js is a utility module that provides straightforward functions for working with asynchronous JavaScript, while Bluebird is a fully-featured Promise library that offers advanced features like cancellation and performance optimizations.

Which one should I use for my project?

It depends on your needs. If you require advanced Promise features and better performance, Bluebird is a great choice. If you need simple async control flow, async.js might be sufficient.

Can you give me an example of how to use Bluebird?

Sure! Here's a simple example:

const Promise = require('bluebird');

const myAsyncFunction = () => {
    return new Promise((resolve, reject) => {
        setTimeout(() => resolve('Done!'), 1000);
    });
};

myAsyncFunction().then(result => console.log(result));
