why tild before x ? ~x ?
u/tomxor

all of the x.method() calls return undefined, and bitwise operators coerce any non-number into 0, so ~x.foo() = ~undefined = ~0 = -1. The purpose of this - all of those method calls are defined as parameters to other methods, not for their return value, but to save 1 char. i.e x.foo(0,0);x.bar()=18 x.foo(0,~x.bar())=17, that the parameter is -1 instead of 0 doesn't matter too much in these cases.

skoehler stole your dweet
u/warbino

ummmm someone stole your code............... his name is skoehler .
u/cantelope

@warbino, @thenize. this may be the last time you are reminded about the spirit of this platform. we do not dwell on "stealing" of code, as remixes are a provided function of the site. Your pattern of edge comments itself, since it continues, may be considered abuse. Unless you stop, there may be action.
