Javascript Algorithm Array Sort Bubble Sort

function bubbleSort(array) {
    for (var i = 0, arrayLength = array.length; i < arrayLength; i++) {
        for (var j = 0; j < arrayLength - 1 - i; j++) {
            if (array[j] > array[j+1]) {
                var temp = array[j];
                array[j] = array[j+1];/* ww w.  j  av a  2  s  . c  o m*/
                array[j+1] = temp;
            }
        }
    }
    return array;
}

let a = bubbleSort([6, 1, 2, 3, 4, 5]); // [1,2,3,4,5,6]
console.log(a);
