23.1.1 The Map Constructor
|
|
|
|
...
|
|
|
|
The Map constructor is designed to be subclassable. It may be used as the
|
|
value in an extends clause of a class definition. Subclass constructors that
|
|
intend to inherit the specified Map behaviour must include a super call to the
|
|
Map constructor to create and initialize the subclass instance with the
|
|
internal state necessary to support the Map.prototype built-in methods.
