I think the answer is D. To add an additional property to a function object, just use the object.property = “property name”.

As I understood – NewOrder is an object prototype, not existing object. If new object would be created (var myOrder = new NewOrder(1,01-01-2017 10:15); ) and that object needs new property, then yes – answer would be D.

I mean that the question is not clear. We can use prototype and normal object extension.
If we use prototype the additional property is permanent, also for future object instances.
If we use normal extensions the additional property is only for that object.
