JavaScript Introduction

In this Module, we will introduce the JavaScript programming language. JavaScript is one of the most popular programming languages in the world. JavaScript is supported by every major web browser and makes web applications like Gmail and Google Maps possible. JavaScript is also popular outside the web browser for creating server-side web applications (Ex: Node.js, which runs JavaScript). While JavaScript is a fairly easy language to pick up if you already know another language such as Java or C# there are enough gotchas to warrant reviewing the language in depth.

TIP

This module will take an estimated 15 - 18 hours to complete.
