Rails 3 recommendations for good javascript tutorials

I am very familiar with javascript and jquery in general, but I am looking for a good guide on how it works in rails 3.0. I understand that the javascript libraries have been rewritten in rails 3. (I never used rails 2.0)

It seems there are no railsguides for thi开发者_如何学Cs.

For Rails tutorials it's often hard to go past Ryan Bates:

• Intro to js in Rails
• Testing JS in rails, same episode revised for coffeescript
• Passing data to JS
• Even Backbone.js in Rails

I found this tutorial useful:
