Code review:
i ? plus.push(i) : --i ? neg.push(i) : zeros.push(i) || printThis() || checkAge() || !!window.MediaSource...

F***ing such a brilliant programmer, spent 4 hours to write it in 1 line, and will take your the guy who replaces you 4 hours to decipher, why are you so adverse to writing #readablecode?!!!

\n is cheap, if(){} is too

This isn't math class where a 3 line proof gets you kudos, stop wasting my time with your genius.
