Wrong. At least Angular JS brings its own jQuery-like functions and does not depend on jQuery by itself.

angularjs uses jquery api , like zepto does it is a hidden dependency. but you are basically using a subset of jquery when you use angularjs.

And Gecko uses most of the WebKit api. We're talking about implementations here, not specs.

the implementation is the same.if you use jQuery script the jQlite code is disabled in AngularJS. it is only possible if the subset code respect all the behavior or the main code. And Gecko doesnt use Webkit api at all. Chrome just cant swap its webkit code to to Gecko without significant rewrite.
