Is there a way to catch assignments to or reads from an undefined property in JavaScript?

JavaScript

JavaScript implements the noSuchMethod callback function for JavaScript Objects.

This function is called whenever JavaScript tries to execute an undefined method of an Object.

I would like to set a callback function to an Object that will be called whenever an undefined property in the Object is accessed or assigned to.

I haven't found a noSuchProperty function implemented for JavaScript Objects and I am curios if there is any workaround that will achieve the same result.
