Congratulations! You finished all of the HTML/CSS material. You are well on your way to becoming a software developer. Next, we are going to dive into JavaScript. JavaScript is the most popular language of the web. Our goal is to give you an understanding of both JavaScript in the browser, and JavaScript as a back-end language using Node.JS. Before we dive in, let's go over what you are going to learn. After completing all (or even part) of this material you'll be ready to start applying to Bootcamps.

What You'll Learn

You'll write and run JavaScript code, and learn how to use JavaScript to manipulate the DOM. Reinforce what you’ve learned by building a web based game. Below is a general overview of what you'll learn in the following JavaScript units.
