Last Thursday Kazuya Namba briefly reviewed Angular.js. On looking it up, I found a number of frameworks. The three most widely used seem to be Angular.js, Backbone.js, and Ember.js. This Google Trends chart compares those three and two more. Here are some pages that compare these and others.

In addition, this looks like a nice intro to Ember.js. 

Here is a Google search for ember.js angular.js, and backbone.js. Here is another that specifically looks for comments on StackOverflow.

A serious introductory tutorial on one or more of these would be a good presentation.
