  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 )

  ...
  5. Let S be ? Get(C, @@species).
  6. If S is either undefined or null, return defaultConstructor.
  7. If IsConstructor(S) is true, return S.
  ...

  24.1.1.4 CloneArrayBuffer ( srcBuffer, srcByteOffset [ , cloneConstructor ] )

  ...
  8. Let targetBuffer be ? AllocateArrayBuffer(cloneConstructor, cloneLength).
  ...

  9.1.14 GetPrototypeFromConstructor

  ...
  3. Let proto be ? Get(constructor, "prototype").
  4. If Type(proto) is not Object, then
     a. Let realm be ? GetFunctionRealm(constructor).
     b. Let proto be realm's intrinsic object named intrinsicDefaultProto.
