ES6 Section 7.3.20 SpeciesConstructor ( O, defaultConstructor )
1. Assert: Type(O) is Object.
2. Let C be Get(O, "constructor").
3. ReturnIfAbrupt(C).
4. If C is undefined, return defaultConstructor.
5. If Type(C) is not Object, throw a TypeError exception.
6. Let S be Get(C, @@species).
7. ReturnIfAbrupt(S).
8. If S is either undefined or null, return defaultConstructor.
9. If IsConstructor(S) is true, return S.
