Essential JavaScript



In this course, you will be provided with an introduction to and acquire experience working with the JavaScript programming language in the environment it's mostly commonly used: the browser. JavaScript is simple and elegant, but is often difficult to work with because it's so different from the programming languages most developers are used to working with.

You'll get answers to these questions:

  • What is JavaScript, how does it relate to other programming languages, and how do you script your web pages with it?
  • How do you traverse and manipulate the DOM and how do you handle events in ways that work in all browsers?
  • What is Ajax and how does JavaScript make it possible?
  • What are closures and prototypes and other exotic features of JavaScript?

Note: You are required to bring your own laptop.
