var copy = $.extend({}, “aString”)
returns an object like this
copy = {
0: “a”,
1: “S”,
2: “t”,…
}
Wouldn't it be nice to return the same string?

I wonder how the non-deep clone would work. Cloning (extending) is always deep if you extend an empty object. Use $.extend(true, {}, obj) to get a clone.

would you provide a clone method like this:
$.clone = function(obj, [deep]) {
return !obj ? obj : $.extend(!deep, {}, obj); //deep clone by default
}

We already mention that in the second paragraph above. I did go in and edit the entry to try to clarify a couple things, so thanks for bringing this to our attention.

don't forget this little tidbit from the old docs: “If no target is specified, the JQuery namespace itself is extended. This can be useful for plugin authors wishing to add new methods to JQuery”
