node.js - Function Overloading on prototype Javascript?

I wanted to know if we can overload a function on prototype object in JavaScript?

function Person(name, family) {
  this.name = name;
  this.family = family;
}

Person.prototype.getFull = function() {

  return this.name + " " + this.family;
};

Person.prototype.getFull = function(someParam) {
  return this.name + " " + this.family;
};


var p =  new Person();
p.getFull();

p.getFull(someparam);
