Write the dependencies of backbone.js in javascript?

The only hard dependency(without which backbone js won't work at all) is Underscore.js. Underscore is a JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.

There are other dependencies required as you proceed to use more advanced features of backbone.js. For example,

• Libraries for RESTful persistence(Backbone.sync)

• History support via Backbone.Router

• DOM manipulation with Backbone.View or Jquery
