Using Array.prototype.sort.call to sort a HTMLCollection

Question

var down=function(a,b){alert(a)}
Array.prototype.sort.call(table.tBodies[0].childNodes,down)
Array.prototype.sort.call([0,1,2,3],down)

Why do I not

Answer 1

My proposal to sort an HTMLCollection is:

window.onload = function() {
  var parentNode = document.getElementById('test-list');
  var e = document.getElementById('test-list').children;
  [].slice.call(e).sort(function(a, b) {
    return a.textContent.localeCompare(b.textContent);
  }).forEach(function(val, index) {
    parentNode.appendChild(val);
  });
}
