Info

After seeing http://jsperf.com/javascript-associative-vs-non-associative-arrays, I thought the test could be improved.

Preparation code

 
<script>
  Benchmark.prototype.setup = function() {
    var arr = [9, 9],
        obj = {
        one: 9,
        two: 9
        },
        one = 9,
        two = 9;
    
    var sum = 0 ;
  };
</script>

Test runner

Warning! For accurate results, please disable Firebug before running the tests. (Why?)

Java applet disabled.

sum = arr[0] + arr[1];

sum = obj.one + obj.two;

sum = one + two;

sum = 9 + 9;
