  22.2.4.3 TypedArray ( typedArray )

  This description applies only if the TypedArray function is called with at
  least one argument and the Type of the first argument is Object and that
  object has a [[TypedArrayName]] internal slot.

  ...
  17. If SameValue(elementType, srcType) is true, then
    a. Let data be ? CloneArrayBuffer(srcData, srcByteOffset).
  ...

  24.1.1.4 CloneArrayBuffer ( srcBuffer, srcByteOffset [ , cloneConstructor ] )

  ...
  2. If cloneConstructor is not present, then
    a. Let cloneConstructor be ? SpeciesConstructor(srcBuffer, %ArrayBuffer%).
  ...

  7.3.20 SpeciesConstructor ( O, defaultConstructor )

  ...
  2. Let C be ? Get(O, "constructor").
  ...
  4. If Type(C) is not Object, throw a TypeError exception.
