	// Write a function that takes an array and an iterator function and applies
	// the function to each element in that array
	//
	// Note: each does not have a return value, but rather simply runs the

	// each([1,2,3], function(val) { console.log(val*val); }) // output 1, 4, 9

	var each = (array, iterator) => {
