clarification for javascriptobject.py

between 8:50 - 9:20 what the class is doing is being explained. I'm getting confused by the explanation. He says when the try is executed and if the key exists we'll get it from the dict. If the key doesn't exist we fall back on the dict version of getattribute(), which will see if there is a real attribute with that name. I think he means say if the JavaScriptObject class had an attribute called name the dict version of getattribute would look for that if the try failed.

Correct. Even when running a method of the inherited class using super(), while the method is in the inherited class, it is operating on the current instance of the derived class JavaScriptObject when looking for an attribute not found during the self[item] lookup.
