1. Assert: length is an integer Number ≥ 0.
2. If length is -0, let length be +0.
3. Let isArray be ? IsArray(originalArray).
4. If isArray is false, return ? ArrayCreate(length).
5. Let C be ? Get(originalArray, "constructor").
6. If IsConstructor(C) is true, then
   1. Let thisRealm be the current Realm Record.
   2. Let realmC be ? GetFunctionRealm(C).
   3. If thisRealm and realmC are not the same Realm Record, then
      1. If SameValue(C, realmC.[[Intrinsics]].[[%Array%]]) is true, let C be undefined.
7. If Type(C) is Object, then
   1. Let C be ? Get(C, @@species).
   2. If C is null, let C be undefined.
8. If C is undefined, return ? ArrayCreate(length).
9. If IsConstructor(C) is false, throw a TypeError exception.
10. Return ? Construct(C, « length »).
