If you're working with Node.js, chances are you've worked with asynchronous operations in JavaScript. But if you're unfamiliar with it, an asynchronous task is an operation executed independently of the main thread in the JavaScript engine. Essentially, this is what lets the application function without a blocking UI.
Behind the scenes, Node.js utilizes the event loop to handle all asynchronous operations, keeping the primary thread available for compute functions.
Well, you'd build asynchronous operations in JavaScript using Promises. A Promise is an object returned by an asynchronous operation representing its progress.
