// Part 1.
// Implement a function prototype extension that caches function results for
// the same input arguments of a function with one parameter.
//
// For example:
// Make sin(1) have the result of Math.sin(1), but use a cached value
// for future calls.
//
// Part 2.
// Use this new function to refactor the code example.

// Exercise 1 - OO || !OO
// Define a data structure for cars (make and color), and a function
// that logs a string like "I'm a red Mercedes" to the console.
// Make two versions: a functional version, and a object-oriented version.

//Two solutions, one with a constructor only, and one using prototypes

// Example call for functional version:
var logCar = function(car) {
  console.log('I\'m a ' + car.color + ' ' + car.make);

// Exercise 2 - Closures
// Wrap the following code in a closure and export only the "countdown" function.

// Code
var index = (function log(){
  console.log(index);
}

function iterate(){
  log();
