title: IE SCRIPT5008: Invalid Left-hand Side in asignment
body: <p>To be fair i copy and pasted this to shuffle an array and works everywhere except in IE i get this error: SCRIPT5008: Invalid left-hand side in assignment (116,5). Points to this line <code>[a[i - 1], a[j]] = [a[j], a[i - 1]];</code></p>
  
  <pre class="lang-js prettyprint-override"><code>function shuffle(a) 
  {
    for (let i = a.length; i; i--) 
    {
      let j = Math.floor(Math.random() * i);
      [a[i - 1], a[j]] = [a[j], a[i - 1]];
    }
  }
