should just return undefined.

Says who? When called with one arg it should be the attribute name as a string, and undefined is not a string. We threw an error so you could find the bug! You're welcome.

I've got to say, this really isn't helpful. Couldn't jQuery do something like:

if (!arguments.length) {

throw new Error('attr requires at least one argument');


That would be MUCH more helpful than the current nebulous error.
