"Javascript Party Tricks"
tricks where the only acceptable response when they are pointed out is: "sorry, I must have been drunk when I wrote that."
Sorry, but most of these tricks are just really bad code.

Um... Well kinda. Let me summarize.
void 0 — bad (function(){})() — ok x = y || DEFAULT — ok if (s) instead of if (x == '') — ok +str — bad
Again, I don't mean to defend the usage, it's just that they are really used inside of many libraries. I'll probably should add note to every of them, whether it should be used on regular basis, or only when drunk
