We've settled on nodeType as the DOM node discriminator... I'd say that means replacing !tween.elem.style with tween.elem.nodeType !== 1 here, and tween.elem.style with tween.elem.nodeType === 1 in set. There's also some rearranging to make them more compressible, but that can come after the logic update.

+cc @jquery/core What is the max line length?

Do not change jscsrc, it was already defined correctly - http://contribute.jquery.org/style-guide/js/#spacing

Lines should be no longer than 80 characters, and must not exceed 100 (counting tabs as 4 spaces). There are 2 exceptions, both allowing the line to exceed 100 characters:

100, search the string "Lines should be" here https://contribute.jquery.org/style-guide/js/ :)
oh crap, I didn't refresh my page.

I tried searching the style guide for it, but my find fu was poor I suppose...

So if it was "defined correctly" why wasn't it erroring on my long lines?

Reverted this change, found that the new version of jscs works - but grunt doesn't run it...

😦 -- such a pain to follow our style guide right now when the tooling isn't up to date.

This now checks actual unit tests too, right?

Just the ones I added now, the others are still dirty.

Well, it says "only test helpers"

you suggesting I just nuke the comment?

// TODO: Enable all tests, for now, test helpers and the ones that pass are included

something like that seems alright.
