title: property forEach does not exist on type NodeListOf
body: <p>Angular 2.4.4, TypeScript 2.1.5, PhpStorm 2017.2.1
  I write this code:</p>
  
  <pre><code>const list = document.querySelectorAll('path.frame-zone');
  list.forEach(() =&gt; {
  </code></pre>
  
  <p>But the second line is underlined with a red line and TsLint reports that "property forEach does not exist on type NodeListOf"
  But when I ctrl+click the <code>forEach</code> it gets me to <code>lib.es6.d.ts</code> where <code>forEach</code> is declared for <code>interface NodeListOf&lt;TNode extends Node&gt;</code></p>
  
  <p>Why it won't let me use it? What is wrong?</p>
