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

...
23. Return O.
