JavaScript from a high level, answering questions such as "What is it?" and "What can you do with it?", and making sure you are comfortable with JavaScript's purpose.

Prerequisites: Basic computer literacy, a basic understanding of HTML and CSS.

Objective: To gain familiarity with what JavaScript is, what it can do, and how it fits into a web site.

A high-level definition

JavaScript is a scripting or programming language that allows you to implement complex features on web pages — every time a web page does more than just sit there and display static information for you to look at — displaying timely content updates, interactive maps, animated 2D/3D graphics, scrolling video jukeboxes, etc. — you can bet that JavaScript is probably involved. It is the third layer of the layer cake of standard web technologies, two of which (HTML and CSS) we have covered in much more detail in other parts of the Learning Area.

Javascript is the language that modern developers need to know, and know well. Truly knowing Javascript will get you a job, and enable you to build quality web and server applications. In this course you will gain a deep understanding of Javascript. You'll learn the foundations of how to build your own Javascript framework or library. We start with the basic fundamentals and work our way to advanced programming WITHOUT relying on frameworks or libraries at all. You will learn a ton of pure JavaScript, whether you are a beginner or an established JS programmer.
