description: >
If trap is undefined, propagate [[Construct]] to target,
passing correct newTarget parameter
info: |
[[Construct]] ( argumentsList, newTarget )
[...]
7. If trap is undefined, then
b. Return ? Construct(target, argumentsList, newTarget).
Construct ( F [ , argumentsList [ , newTarget ] ] )
[...]
5. Return ? F.[[Construct]](argumentsList, newTarget).
[[Construct]] ( argumentsList, newTarget )
[...]
5. If kind is "base", then
a. Let thisArgument be ? OrdinaryCreateFromConstructor(newTarget, "%ObjectPrototype%").
OrdinaryCreateFromConstructor ( constructor, intrinsicDefaultProto [ , internalSlotsList ] )
[...]
2. Let proto be ? GetPrototypeFromConstructor(constructor, intrinsicDefaultProto).
3. Return ObjectCreate(proto, internalSlotsList).
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.
GetFunctionRealm ( obj )
[...]
2. If obj has a [[Realm]] internal slot, then
a. Return obj.[[Realm]].
