24.2.2 The DataView Constructor
...
The DataView 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 DataView behaviour must include a super call
to the DataView constructor to create and initialize subclass instances with
the internal state necessary to support the DataView.prototype built-in
methods.
