Hi everyone! In this video, we cover the many aspects of working with Promises in JavaScript. We discuss the basic syntax of promises, how promises can be used instead of callbacks for asynchronous execution, and the specifics of working with .then() and .catch().

This video is part of a JavaScript introductory course for beginners, where I will take you through all the most important JavaScript concepts, as well as several best practices for the language. Here is the playlist for the whole JavaScript introduction course:

The course has an interactive online platform where you can practice everything we discuss during the videos:
