Backbone.js

Backbone.js is a JavaScript rich-client web app framework based on the model–view–controller design paradigm, intended to connect to an API over a RESTful JSON interface. Backbone has only hard dependency, which is on one JavaScript library,^[2] Underscore.js,. jQuery can also be optionally used for the library.^[3] It is designed for developing single-page web applications,^[4] and for keeping various parts of web applications (e.g. multiple clients and the server) synchronized.^[5] Backbone was created by Jeremy Ashkenas, who is also known for CoffeeScript and Underscore.js.

When handling the DOM Backbone.js adopts an imperative programming style, in contrast with a declarative programming style (common in AngularJS using data-attributes).^[6] Trying to provide "the minimal set of data-structuring (models and collections) and user interface (views and URLs)",^[7] leaves to the developer the choice of extensions for enhanced functionality. For example, one can use nested views with Backbone Layout Manager or model-view binding with ReSTbasis.
