Using functional libraries with other JavaScript modules

Web applications are made up of all sorts of things: frameworks, libraries, APIs and more. They can work along side each other as dependents, plugins, or just as coexisting objects.

Backbone.js
- An MVP (model-view-provider) framework with a RESTful JSON interface
- Requires the underscore.js library, Backbone's only hard dependency
jQuery
- The Bacon.js library has bindings for mixing with jQuery
- Underscore and jQuery complement each other very well
Prototype JavaScript Framework
- Provides JavaScript with collection functions in the manner closest to Ruby's Enumerable
Sugar.js
- Modifies native objects and their methods
- Must be careful when mixing with other libraries, especially Prototype
