Absolutely the shortest possible, no doubt about it. Try it online!. It won't work in the online one, copy it from there and paste it in the developer console if you are on chrome (as it uses the alert function). Please excuse my absolutely awful ascii art.

I also now see that this output isn't accepted (needs the comma and exclamation mark)... lol now it's time to figure out how I did this months ago so I can fix it ...

You can golf this pretty easily by removing all the whitespace. I'm not sure what restricted character set you've decided to program this under, since it has quotes and an x in it, both of which could surely be used elsewhere to make it shorter.
