bubble sort technique javascript code example

Example 1: bubble sort javascript

function bubblesort(array) {
    len = array.length;

    for (let i = 0; i < len; i++) {
        for (let j = 0; j < len - i; j++) {
            let a = array[j];
            if (a != array[-1]) {
                var b = array[j + 1];
                if (a > b) {
                    array[j] = b;
                    array[j + 1] = a;
                }
            }
        }

let array = [10, 9, 8, 7, 6, 5, 4, 3, 2, 1];
bubblesort(array);
console.log(array)

Example 2: javascript bubleshort example

// 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;
            }
        }
    }
    return arr;
}

// like using Array.sort();
function bubbleSort(arr) {
    for (let i = 0; i < arr.length - 1; i++) {
        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;
            }
        }
    }
