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 or lesser than zero? no
    2. == is fucky and to it null only equals undefined and undefined only equals null (and themselves), so no
    3. is zero bigger than or equal to zero? yeah
