esid: sec-finalization-group-target
description: Default [[Prototype]] value derived from realm of the newTarget
info: |
FinalizationGroup ( cleanupCallback )
...
3. Let finalizationGroup be ? OrdinaryCreateFromConstructor(NewTarget, "%FinalizationGroupPrototype%", « [[Realm]], [[CleanupCallback]], [[Cells]], [[IsFinalizationGroupCleanupJobActive]] »).
...
9. Return finalizationGroup.
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.
