title: MooTools and JQuery Side by Side
body: <p>I just inherited some web pages which uses MooTools. I never used MooTools. Now I need to add some functions on the page, I wonder if it's a good idea to use jquery and mooTools on the same page?</p>
  
  <p>Basically, I have 3 options,</p>
  
  <ol>
  <li>Convert the pages to JQuery, which I have to learn MooTools to do that.</li>
  <li>Write new functions in MooTools. I have to learn even more MooTools to achieve this.</li>
  <li>Use both on the page.</li>
  </ol>
  
  <p>Your opinion will be appreciated.</p>
