What does /// <reference path="jquery-1.8.3.js" /> actually do?
<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>
