Revision 125 of this benchmark created on

Description

This is comparing the runtimes of substr, substring, and slice in a string for large (10000 character) string size.

Preparation HTML

<script>
  var longString = "";
  // Large = 10,000
  for (var i = 0; i < 10000; i++) {
        longString += i % 10;
  }
</script>
