This can be problematic if the product depends on existence or non-existence of certain attributes, or uses pre-defined attributes of object prototype (such as hasOwnProperty, toString or valueOf).\nThis weakness is usually exploited by using a special attribute of objects called proto,  constructor or prototype.
