title: jshint "function" is defined but never used or how to declare a function
body: <p>im getting the jshint notification 
      line 1 col 10  'popUp' is defined but never used.</p>
  
  <p>the js looks like that:</p>
  
  <pre><code>function popUp(e, element) {
      do.something();
  };
  </code></pre>
  
  <p>it would be easy to change the jshint config to </p>
  
  <pre><code>/* jshint unused:false */ 
  </code></pre>
  
  <p>but i want to see if there are other variables which arent used?</p>
  
  <p>do i have to improve my function declartion or is it jshint?</p>
  
  <p>edit</p>
  
  <p>i boiled it down to two failures, these are the functions who are called  in the html file onmousemove or mouseover...</p>
