12. Let O be ? OrdinaryCreateFromConstructor(NewTarget, "%DataViewPrototype%",
« [[DataView]], [[ViewedArrayBuffer]], [[ByteLength]], [[ByteOffset]] »).

17. Return O.
9.1.13 OrdinaryCreateFromConstructor ( constructor, intrinsicDefaultProto [ ,

2. Let proto be ? GetPrototypeFromConstructor(constructor,
intrinsicDefaultProto).
3. Return ObjectCreate(proto, internalSlotsList).

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.
5. Return proto.
