Info

The test is more useful when the values are already set. On chrome, typed arrays are slower than normal arrays in this case!

Preparation code

<script>
  var classic = new Array(500);
  
  var unfixed = new Int8Array(); // Don't do this
  var fixed = new Int8Array(500);
  
  for (var i = 0; i < 500; ++i) {
   classic[i] = 0;
   unfixed[i] = 0;
   fixed[i] = 0;
  }
</script>
