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%).
...
8. Let targetBuffer be ? AllocateArrayBuffer(cloneConstructor, cloneLength).
...
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.
...
24.1.1.1 AllocateArrayBuffer ( constructor, byteLength )
...
1. Let obj be ? OrdinaryCreateFromConstructor(constructor,
"%ArrayBufferPrototype%", « [[ArrayBufferData]], [[ArrayBufferByteLength]] » )
