isFormatable

isFormatable(): Boolean;

The isFormatable method of the Date primitive type returns true for dates that can be formatted correctly by using the shortFormat and longFormat methods of the Date primitive type; otherwise it returns false.

The formatting methods in JADE depend on the operating system date conversion routines, which result in the isFormatable method returning true for dates in the range 1 January 1601 through 31 December 30827.
