Announcing Backbone.js: Models, Collections and Views in 2.4kb
Sorry, I'm a little late to the party with respect to javascript. Could someone please explain to me what this means in english?Backbone  supplies structure to JavaScript-heavy applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing application over a RESTful JSON interface.
