Function Constructor
var Person = function(name, yearOfBirth, job){ this.name = name; this.yearOfBirth = yearOfBirth; this.job = job; } var john = new Person('john', 1967, 'teacher'); john.calculateAge();
Adding Inheritance
The calculateAge was taken out of the constructor and added to the protoype so other instances of person could use it without it being a part of the person function constructor.
Person.protoytpe.calculateAge = function() { console.log(2016 - this.yearOfBirth); }
