Wow, you got downvoted for being 100% right. Nothing in the first sentence nor the first code example is right. I haven't bothered to look at the rest ^^
JS doesn't pass everything by reference. As you've shown in your code example. And JS doesn't actually pass anything by reference as you and Amarshal have shown in your comments (which I knew, but didn't at the same time... Thanks for enlighting me guys!).
But what's mind blowing is that the code example given doesn't actually have anything to do with pass by ref of value. It's checking that the attributes of objects are reference based. It's not actually checking the function argument. Just an attribute of the argument.
I've upvoted your comment and your subcomment/reply. Not that you or anyone cares. They're just points. But it's a shame your comment is being greyed out.
