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?

Basically, I have 3 options,

  1. Convert the pages to JQuery, which I have to learn MooTools to do that.
  2. Write new functions in MooTools. I have to learn even more MooTools to achieve this.
  3. Use both on the page.

Your opinion will be appreciated.
