    The one option that is mandated by an ISO standard.

    Besides, if max and min are going to have a value without any parameter, it has to be exactly those Javascript uses. Unless you have a type that define other bounds for your numbers. And null always have a pointer type (that is object in Javascript), for the same reason that NaN always have a number type.

    The only one that is bad on that list is D.

      Maybe D is too single quotes 0 == ''

      typeof null === "object" was actually a bug in the early implementations, and they decided to keep it in the spec: https://2ality.com/2013/10/typeof-null.html

          We had one null, yes. But what about second null?
