property

A simple example using a built-in javascript object: navigator.my_new_property = "some value"; //can we detect that this new property was added?

I don't want to constantly poll the object to check for new properties. Is there some type of higher level setter for objects instead of explicitly stating the property to monitor?

Again, I don't want to detect if the property value changed, but rather when a new property is added.

Ideas? thanks
