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.
