title: Object doesn't support property or method 'fill'
body: <p>I cannot find same problem online. IE 11 gives error "Object doesn't support property or method <code>fill</code>".</p>
  
  <pre><code>var arr = new Array(5);
  arr.fill(false);
  </code></pre>
  
  <p>Is there any convenient way to to fill an array instead of using a <code>for</code> loop? Thanks.</p>
