I have a fairly large codebase that depends on MooTools v1.11 and am about to convert to version 1.2. Since this is a pretty major overhaul, I've toyed with the idea of converting to jQuery.
Anyone have advice on whether to update to jQuery or just stick with MooTools?
I mostly use MooTools for Ajax, drag and drop, and some minor effects.
If it's not broken. Don't fix it.
jQuery might have X or Y but if everything is dependent on MooTools, you might have a lot of work ahead of you to convert from MooTools.
Keep MooTools if you used it extensively through out your site. However, if you only have 2-3 pages with minor effects... the change might be worth it.
