In Javascript, NaN (not a number) is a number:

  >> typeof NaN
  <- "number"

Let's see then:

  >> (NaN % 2) == 0
  <- false

So clearly NaN is odd. /s

(And if you're thinking "you gotta equals harder":

  >> (NaN % 2) === 0
  <- false

Nope, still odd.

Both of the infinities are also odd by the same logic, too, if you were curious.

null and false are even. true is odd. [] is even, [0] is even, [1] is odd.)
