The contents of the string are implementation dependent, but are intended to represent the "date" portion of the Date in the current time zone in a convenient, human-readable form. We can't test the content of the string, but can verify that the string is parsable by Date.parse The toDateString function is not generic; it generates a runtime error if its 'this' value is not a Date object. Therefore it cannot be transferred to other kinds of objects for use as a method.
