JQuery and YUI, can they live together?

Question

Can JQuery and YUI live together w/o any conflicts?

Answer 1

Yes. They live in different namespaces, plus jQuery has a noConflict option.

Answer 2

Yes YUI3 uses YUI object, jQuery uses $. For instance you can use YUI 3 Test module and inside it using $ for DOM manipulation/traversing (I think jQuery is really good for those purposes), so for instance you can do:

YUI().use("test", function(){
    test : function() {
       $('div li').addClass("example");
       Y.Assert.areEqual("example", $('div li').attr("class"));
    }
});
