Let me introduce you to Classical Inheritance that never uses prototype. This is a bad coding exercise but will teach you the real Classical Inheritance which always compared to prototypal inheritance:

Make a custructor:

function Person(name, age){
  this.name = name;
  this.age = age;
  this.sayHello = function(){return "Hello! this is " + this.name;}
}
