21.1.1 The String Constructor
...
The String 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 String behaviour must include a super call to
the String constructor to create and initialize the subclass instance with a
[[StringData]] internal slot.
