Take your JavaScript skills to the next level with this class, which will build on skills learned in Introduction to JavaScript and take those skills to new and deeper levels.

This class is held in three sessions:

• November 6, 11am-4pm

• November 13, 11am-4pm

• November 20, 11am-4pm

All three sessions are included in the $96 class fee. Please plan on attending all 3 weeks of the class.

In this class we'll cover:

• Variables, including scope, local variables, global variables, and the this keyword. This is a review and a deeper dive into variables than we covered in intro to JS.

• Arrays, including map and filter functions. Again, this is a review and then a deeper dive than covered in intro to JS.

• Functions, including closures, passing functions as arguments, returning functions. A review of what we know already, then a deeper look at functions.

• Objects, including different ways to create objects, the difference between arrays and objects, the built-in objects and the global object. A review of what we learned in intro to JS, then a deeper look at objects.

• Object-oriented JavaScript, including prototypes and inheritance

• Advanced DOM Manipulation, including event delegation and making use the command line and developer tools

• Ajax and JSON - including how to make asynchronous calls, parse JSON responses, and update the UI


You must have a working knowledge of HTML and CSS, and a good knowledge of the concepts introduced in intro to JavaScript. If you know some JavaScript but aren't sure if you should enroll in Intermediate JavaScript, please review the JavaScript 101 slides ( to see if you feel comfortable with the information presented and are able to work through the exercises, both the in-class exercises and the homework assignments.
