title: What does /// <reference path="jquery-1.8.3.js" /> actually do?
body: <p>I see this line of code in some of the JavaScript Files I work with, at the very top of the file ( first line ), but its not clear to me exactly what this does.  </p>
  
  <p>Google wasn't much help on this.</p>
  
  <pre><code>/// &lt;reference path="jquery-1.8.3.js" /&gt;
  </code></pre>
  
  <p>What is the purpose of it?  </p>
  
  <p><em>To add more details, I am using Visual Studio 2015.</em> </p>
