Javascript frameworks

I started a separate page to collect this information in one place. See also: HTML5, CSS and Javascript and PHP frameworks.

Angular.js - MVC like javascript framework.

Backbone

Ember

JQuery

Knockout - based on MVVM. It is lightweight. Focus is on data binding.

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