    console.log("------------------------------------------------------------")

    console.log("newObj.deepProperty.p1: ", newObj.deepProperty.p1);

    console.log("newObj2.p1: ", newObj2.p1); 
    console.log("newObj2.deepProperty.p1: ", newObj2.deepProperty.p1);

})();

The idea here is to use two know design patterns factory methods and prototype to create deep copies of javascript objects.
The factory is responsible for creating the object structure whereas the clone method decides which complex attributes to clone.
