Problem {8} - Sort Array (bojanm - mod1)

var arr1 = [5, 4, 3, 2, 1];
var arr2 = [12, 12, 50, 2, 6, 22, 51, 712, 6, 3, 3];
function sortArray(arr) {
    var endOf = 0;
    var tempElm;
    var elmIndex;
    do {
        tempElm = arr[endOf];
        for (i = endOf; i < arr.length; i++) {
            if (tempElm <= arr[i]) {
                tempElm = arr[i];
                elmIndex = i;
            } else {
                continue
            }
        }
        arr.splice(elmIndex, 1);
        arr.unshift(tempElm);
        endOf = endOf + 1;
    } while (endOf != arr.length);
    console.log(arr)

}
sortArray(arr2);
