description: Default [[Prototype]] value derived from realm of the newTarget

info: |

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.
