//*** Is STRING a Valid Date? ***
approach: check if .getTime is equal to itself; WTF?
because if date is invalid, it will return NaN for .getTime();
You can a) check isNaN(.getTime()) or (b) NaN is never equal to itself;
; i.e. return .getTime() === .getTime() is true, if valid date; false if not date - haha WTF indeed.
