title: Difference between jquery and $
body: <p>I did heavy use of jquery on my php project. But on some page the <code>$</code> is not working, so I have to use jquery. For example:</p>
  
  <pre><code>jQuery('#mycarousel').jcarousel({
  start: 3
  });
  </code></pre>
  
  <p>Can anybody please tell me what is the difference between $ and jquery?</p>
