Few Tricks on Compressing Js13k Entry

Most important detail: in js13k entry 13k stands for zipped entry size. And this detail makes js13k differ from other code golfing compos.

Last year winner entry uncompressed size was about 70k. 70 kilobytes! In js1k you have a month to minify 1k, so how much time would it take to minify 70k? Nope, you have only 1 month. So it's very unlikely one will manually golf the entry. And this is the other thing that makes js13k special: no hardcore manual "hell yeah I've stripped one byte!" golfing.
