WeakRef( target )
...
3. Let weakRef be ? OrdinaryCreateFromConstructor(NewTarget, "%WeakRefPrototype%", « [[Target]] »).
4. Perfom ! KeepDuringJob(target).
5. Set weakRef.[[Target]] to target.
6. Return weakRef.
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.
