6. Let A be ? TypedArraySpeciesCreate(O, « len »).

4. Return ? TypedArrayCreate(constructor, argumentList).
22.2.4.6 TypedArrayCreate ( constructor, argumentList )
...
3. If argumentList is a List of a single Number, then
a. If the value of newTypedArray's [[ArrayLength]] internal slot <
argumentList[0], throw a TypeError exception.
