description: Default [[Prototype]] value derived from realm of the NewTarget.
info: |
Array ( )
...
3. If NewTarget is undefined, let newTarget be the active function object; else let newTarget be NewTarget.
4. Let proto be ? GetPrototypeFromConstructor(newTarget, "%Array.prototype%").
5. Return ! ArrayCreate(0, proto).
GetPrototypeFromConstructor ( constructor, intrinsicDefaultProto )
...
3. Let proto be ? Get(constructor, "prototype").
4. If Type(proto) is not Object, then
a. Let realm be ? GetFunctionRealm(constructor).
b. Set proto to realm's intrinsic object named intrinsicDefaultProto.
5. Return proto.
