Course description

In this 6 part learning series you’ll learn about JavaScript. JavaScript is a web scripting language that allows you to build dynamic web pages and add interactivity to your site. The course covers very basic JavaScript techniques and terminology all designed to give you a solid grounding in JavaScript’s capabilities and concepts. It starts with the basic elements of the JavaScript language and builds up to working with JavaScript in the browser. You will learn how to alter site content, add behaviors like clicks and key presses, and commands for interacting with a web server.

The courses should be taken in the following order; JavaScript for Designers: Overview & Language; JavaScript for Designers: Operators, Variables, & Arrays; JavaScript for Designers: Functions, Objects, & Methods; JavaScript for Designers: Scope, Hoist, Pitfalls, & HTML; JavaScript for Designers: DOM, jQuery, Functions, & OOP and JavaScript for Designers: Closures, Methods, & Libraries.
