Quote (note typo in second item): 1. A property cannot be added as or modified to be non-configurable, if it does not exists as a non-configurable own property of the target object. 2. A property may not be non-configurable, if is corresponding configurable property of the target object exists. Question: Doesn’t #1 imply #2? -- Dr. Axel Rauschmayer a...@rauschma.de rauschma.de
