Questions tagged [backbone.js]

Backbone.js is a JavaScript framework with a RESTful JSON interface and is based on the model–view–presenter (MVP) application design paradigm

Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich of enumerable functions, views with declarative event handling, and connects it all to your existing API over a interface.

Its only hard dependency is Underscore.js, and as such some questions and answers tagged Backbone.js may in fact pertain to specifics. As an alternative, Lodash is also supported.

It also depends on jQuery, but supports Zepto.
