  <li><p>Those implementations have been explained since 2011. </p></li>
  <li><p>When ES6 came , there are many code become more <strong>elegant</strong> &amp; <strong>performance</strong>  . </p></li>
  <li><p>Concerning <strong>String</strong> reversing , I am wondered, if ES6 supports it . </p></li>
  <li><p>Anyway, i end up with this syntax : </p>
