title: What is this JavaScript reference syntax used in Visual Studio?
body: <p>In Visual Studio 2012, I created a web application then found the following line in the default <strong>_references.js</strong> script that came with the project:</p>
  
  <pre><code>/// &lt;reference path="jquery-1.8.2.js" /&gt;
  </code></pre>
  
  <p>What is this reference notation doing? This is confusing - isn't this just a comment, which shouldn't do anything? As I understand, a double slash (//) comments out a line in JavaScript. Is there anything special about triple-slash comments?</p>
