Can someone explain this? I mean, the last result. Usually I can at least understand Javascript's or PHP's quirks. But this time I'm stumped.

JS null and undefined shenanigans


basically:

  1. bigger an lesser comparison types convert null to zero, so is zero bigger than zero? no
  2. == is fucky and to it null only equals undefined and undefined only equals null, so no
  3. is zero bigger than or equal to zero? yeah

I'm starting to think JS maintainers have a thing against mathematicians

My only thought here might be >= is usually the same as !< and maybe thats how it is defined in javascript and since < is false than >= == !false == true
