Now that you had the benefit of hindsight and coupled with your experience in squeezing out performance, do you have any opinion on Backbone vs Angular from a pure performance perspective?
As much as we would love to speak to that, we've unfortunately haven't done this same type of benchmarking/analysis on backbone.js. This was our first foray into a Javascript MVC-ish frameworks. After doing the paper research into AngularJS and its peers, we decided to give AngularJS a whirl by coding up this acid test and only going through the alternatives if AngularJS didn't work out.
