...
2. Let asyncDisposableStack be ? OrdinaryCreateFromConstructor(NewTarget, "%AsyncDisposableStack.prototype%", « [[AsyncDisposableState]], [[DisposeCapability]] »).
3. Set asyncDisposableStack.[[AsyncDisposableState]] to pending.
4. Set asyncDisposableStack.[[DisposeCapability]] to NewDisposeCapability().
5. Return asyncDisposableStack.
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.
