          if (sortedArray[i - 1] > sortedArray[i]) {
            [sortedArray[i], sortedArray[i - 1]] = [sortedArray[i - 1], sortedArray[i]];
            swap = true;

// like using Array.reverse();
function bubbleReverse(arr) {
    for (let i = arr.length - 1; i > 0; i--) {
        for (let j = arr.length - 1; j > 0; j--) {
            if (arr[j] > arr[j - 1]) {
                let temp = arr[j];
                arr[j] = arr[j - 1];
                arr[j - 1] = temp;
            }
        }

// like using Array.sort();
function bubbleSort(arr) {

        for (let j = 0; j < arr.length - 1; j++) {
            if (arr[j] > arr[j + 1]) {
                let temp = arr[j];
                arr[j] = arr[j + 1];
                arr[j + 1] = temp;
