Backbone.js is a light weight framework that provides a RESTful JSON interface for data models, views, collections, and events. Backbone.js is used on over 12,000 websites according to Libscore including Linkedin, Pinterest, ESPN, Walmart, Target and Best Buy.

- From the Backbone.js website: Backbone’s only hard dependency is Underscore.js ( >= 1.7.0) also created by Jeremy Ashkenas. For RESTful persistence and DOM manipulation with Backbone.View, include jQuery ( >= 1.11.0).
- Libraries such as Lo-Dash instead of Underscore.js and Zepto instead of jQuery work with varying degrees of compatibility.
