Bubblesort Implementation in Java Script

Bubblesort.js

function swap(array, i, j){
    var aux = array[i];
    array[i] = array[j];
    array[j] = aux;
}

function bubbleSort(array, ascending){	
    for(i = 0; i < array.length; i++){
        for(j = array.length - 1; j >= i + 1; j--){
            if((array[j] < array[j - 1]) === ascending){
                swap(array, j, j - 1);
            }
        }
    }
}

var array = [5, 4, 3, 2, 1, 0];

console.log("ANTES: " + array);
bubbleSort(array, true);
console.log("DEPOIS: " + array);
