title: How can I get typings when I import a js library with a `<script src`... tag?
body: <p>I'm using polymer to import external javascript libraries that export as a global variable like so:</p>
  
  <pre><code>&lt;script src="/path/to/library"&gt;&lt;/script&gt;
  &lt;script&gt;
      theLibrary.something // `theLibrary` is a global exported from the script tag above
  &lt;/script&gt;
  </code></pre>
  
  <p>I'm a bit new to polymer and I've been previously working in a typescript environment, so long story short: I miss my typings.</p>
  
  <p>Is there anyway to get the typings inside the <code>&lt;script&gt;</code> tags of the HTML or get typings any way at all in a Polymer element?</p>
