Bubble Sort Algorithm

bubble_sort.js

function sortItems(array) {
	for (let i = 0; i < array.length; i++) {   // for loop iterates through each item in the array;
		for (let j = 0; j < array.length; j++) {   // for loop makes comparisons between each element in the array;
			if (array[j] > array[j + 1]) {   // if statement checks if the number on the left of a comparison is greater than the number on the right;
				let temp = array[j];   // if it is, we swap the numbers; otherwise, do nothing.
				array[j] = array[j + 1];
				array[j + 1] = temp;
			}
