Most efficient way to convert an HTMLCollection to an Array

Question

Is there a more efficient way to convert an HTMLCollection to an Array, other than iterating through the contents of said collection and manually pushing each item into an a

Answer 1

This is my personal solution, based on the information here (this thread):

var Divs = new Array();    
var Elemns = document.getElementsByClassName("divisao");
    try {
        Divs = Elemns.prototype.slice.call(Elemns);
    } catch(e) {
        Divs = $A(Elemns);
    }

Where $A was described by Gareth Davis in his post:

function $A(iterable) {
  if (!iterable) return [];
  if ('toArray' in Object(iterable)) return iterable.toArray();
  var length = iterable.length || 0, results = new Array(length);
  while (length--) results[length] = iterable[length];
  return results;
}

If browser supports the best way, ok, otherwise will use the cross browser.
