So, congratulations, @jashkenas and everyone who has invested their effort in Backbone – it’s great to see it come to fruition!
Coincidentally, I picked up Backbone.js in earnest just last week; I’ve been building on Piotr Walczyszyn‘s Backbone.Force plugin, which implements a Backbone Model and Collection to pull data from Force.com via ForceTK and the REST API. The fact that it only took a few hours to extend Backbone.Force to support RemoteTK is a testament to both the quality of the Backbone framework and Piotr’s work. Check out
my work in progress the new Mobile Pack on GitHub.
