//start IIFE
(function () {
//Person Constructor
function Person(name, age) { = name;
this.age = age;
//Sample people
var personOne = new Person('Luke', 24);
var personOne = new Person('Leia', 24);
//Prototype added to Person Constructor
Person.prototype.calculateBirthYear = function(currentYear){
//do something
console.log(currentYear - this.age);
//Call function
personOne.calculateBirthYear(2018); //logs to the console: 1994
//close IIFE
