Deprecated Object.prototype._lookupSetter_() JavaScript provides constructor functions for many built-in language objects: like Date for dates, Set for sets and others that we plan to study. JAVASCRIPT CONSTRUCTOR HOW TOIn this case, if the constructor has 3 arguments, how to pass only the third parameter. In case of Javascript, we can have only one constructor.

It will create an empty object if null or undefined is passed. Deprecated Object.prototype._defineSetter_() Javascript Object Oriented Design - Javascript Constructor inheritance.
