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.
...
18. Else,
a. Let bufferConstructor be ? SpeciesConstructor(srcData, %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.
