  22.2.4 The TypedArray Constructors

  ...

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