JavaScript method to sort an array

Took 5 minutes and 2 seconds to code JavaScript method to return a sorted array. Here is the code snippet.

Code:

arr = [3, 5, 2, 4];

function sort(arr) {

for (var i = 0; i < arr.length; i++) {

for (var y = i + 1; y < arr.length; y++) {

if (arr[i] > arr[y]) {

k = arr[i];

arr[i] = arr[y];

arr[y] = k;

}

}

}

return arr;

}

document.write(sort(arr));

Result:

2,3,4,5
