Angular VS Knockout VS Ember VS Backbone

JavaScript performance comparison

Revision 175 of this test case created by Andy Kant

Info

Comparison between Angular, Knockout and Ember. Updated Backbone to use a collection, in order to be more fair. Also with comparison of optimization during object creation.
