With Backbone, you represent your data as Models, which can be created, validated, destroyed, and saved to the server. Whenever a UI action causes an attribute of a model to change, the model triggers a “change” event; all the Views that display the model’s state can be notified of the change, so that they are able to respond accordingly, re-rendering themselves with the new information. In a finished Backbone app, you don’t have to write the glue code that looks into the DOM to find an element with a specific id, and update the HTML manually — when the model changes, the views simply update themselves.
Backbone was developed by Jeremy Ashkenas, same person who also built CoffeeScript. Many websites have started to use Backbone framework, such as Digg, Rdio, Hulu etc..
