Get last character from string (v3)

Revision 3 of this benchmark created by me on

Setup

var strlen = 11;
  function charAt(str) {
      return str.charAt(str.length - 1);
  }
  function charAtCached(str) {
      return str.charAt(strlen - 1);
  }
  function index(str) {
      return str[str.length - 1];
  }
  function slice(str) {
      return str.slice(-1);
  }
  function substr(str) {
      return str.substr(-1);
  }
  function charCodeAt(str) {
      return str.charCodeAt(str.length - 1);
  }
  function charCodeAtCached(str) {
      return str.charCodeAt(strlen - 1);
  }
