20.3.2 The Date Constructor
|
|
|
|
...
|
|
|
|
The Date constructor is a single function whose behaviour is overloaded based
|
|
upon the number and types of its arguments.
|
|
|
|
The Date constructor is designed to be subclassable. It may be used as the
|
|
value of an extends clause of a class definition. Subclass constructors that
|
|
intend to inherit the specified Date behaviour must include a super call to
|
|
the Date constructor to create and initialize the subclass instance with a
|
|
[[DateValue]] internal slot.
