Hi again! In this video, we finish our discussion on functions by talking about how to handle parameters and return values. We cover many cases that can happen when passing arguments to a function in JavaScript, and detail how to correctly handle each of them.

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:
