	// Merge Sort Implentation (Recursion)
	function mergeSort (unsortedArray) {
	// No need to sort the array if the array only has one element or empty
	if (unsortedArray.length <= 1) {
	return unsortedArray;
	}
	// In order to divide the array in half, we need to figure out the middle
	const middle = Math.floor(unsortedArray.length / 2);

	// This is where we will be dividing the array into left and right
