What UI framework is http://mega.co.nz/ using?

Question

I am interesting in what framework http://mega.co.nz/ is using. Specifically instantaneous page/section transitions with urls like :/#/pagename and smooth transition effects. Also form input handling is slick.

Answer 1

Backbone jQuery, loaded with requirejs and compiled in main.js with r.js. Instead of underscore.js it uses lodash.

There are also these jquery plugins used: jquery.easing, jquery.jscrollpane, jquery.mousewheel, jquery-validate, jquery-placeholder.

The scrolling feature is implemented using jScrollPane.
