title: Error: "Uncaught SyntaxError: Unexpected token (", makes no sense to me
body: <p>My code: </p>
  
  <pre><code>&lt;script&gt;
  
  (function() {
      var box = $('div.box'),
  
      $('button').on('click', function(){
          box.animate({
              'fontSize': '+=5',
              'width': '+=300'
          }, 500, 'swing', function(){}
          });
      });
  
  })(); 
  
  
  &lt;/script&gt;
  </code></pre>
  
  <p>The code does not work for me, however it does for the tutorial I am watching on youtube: <a href="https://www.youtube.com/watch?v=dnk3pbW6s6Y" rel="nofollow">https://www.youtube.com/watch?v=dnk3pbW6s6Y</a></p>
  
  <p>If someone could help me solve this, it would be great.</p>
