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.

Eye of the beholder... 👁️ 👁️

u/cantelope

that "eye of the beholder" platitude does not account for the "other dimension" of ineffable things like beauty, art, literature, etc. There is a dual property which defines the quality of some things, being 1) personal preference, and 2) objective quality with respect to its purpose. Neither bit can be truncated or the truth is lost. Nor can the 2 dimensions be forced into a single, linear value. this is why some contests can never be competitions, but are in fact, popularity contests ;)
