// 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.

// Example call for functional version(Couldn't Figure out):  
var logCar = (function(funcCar){
	 return  function(){
	   console.log("I'm a " + funcCar.color + " " + funcCar.make);

Elixir Keyword Lists are a list of two item tuples where the first element of a tuple is an atom

iex(2)> k1 = [{:a, 1}, {:b, 2}, {:c, 3}, {:d, 4}]
[a: 1, b: 2, c: 3, d: 4]

iex(4)> k1 = [a: 1, b: 2, c: 3, d: 4] #a spoonful of sugar
[a: 1, b: 2, c: 3, d: 4]

iex(5)> k1 ++ {:b, 1} #not what we want
[{:a, 1}, {:b, 2}, {:c, 3}, {:d, 4} | {:b, 1}]
