JavaScript Algorithms: Sort a list using Bubble Sort

function swapElement(arr, firstIndex, secondIndex){ var tmp = arr[firstIndex]; arr[firstIndex] = arr[secondIndex]; arr[secondIndex] = tmp; } function bubbleSort(arr){ var len = arr.length, i, j, stop; for (i = 0; i < len; i++){ for (j = 0, stop = len-i; j < stop; j++){ if (arr[j] > arr[j+1]){ swapElement(arr, j, j+1); } } } return arr; } console.log(bubbleSort([30, 3, 90, 150, 45, 63, 27, 18, 12, 999]));
