title: JSHint - Line feed error
body: <p><strong>JSHint</strong> complains when, at the end of the file, there is no line feed. Here is an example:</p>
  
  <pre><code>Missing line feed at file end at app/services/cache.js :
      14 |
      15 |  });
      16 |})();
  -------------^
  </code></pre>
  
  <p>What's the purpose of having this line feed? What difference would it make?</p>
