Fallback to the NewTarget's [[Prototype]] if the prototype property is not an object
|
|
info: |
|
|
AggregateError ( errors, message )
|
|
|
|
1. If NewTarget is undefined, let newTarget be the active function object, else let newTarget be NewTarget.
|
|
2. Let O be ? OrdinaryCreateFromConstructor(newTarget, "%AggregateError.prototype%", « [[ErrorData]], [[AggregateErrors]] »).
|
|
...
|
|
6. Return O.
|
|
|
|
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.
|
|
Return proto.
