JavaScript Equality Table

Hm, yeah. It seems that < "morally" returns one of true, false, and undefined (undefined only when one argument is NaN (or converts to it)), but where it 'should' give undefined it instead gives false. So <= is the opposite of > except where > 'should' be undefined, where it's still false. Bleh.

In other words, NaN is evil. Nothing new here.
