Does jQuery ship with SharePoint?
<p>Currently, we want to upgrade jQuery in our products, so I want to know if SharePoint use jquery in its js? It will help us to make decision about which jquery version we are going to use. I try to find jquery reference in SharePoint 2010, but I didn't find it. Does it mean there is no jQuery in SharePoint?  </p>

<p>I found there is a js called "mQuery.js" in SharePoint 2013, the usage is quite similar with jQuery, and even most of the events'name are same. Why does Microsoft create a js for SharePoint 2013 instead of using jQuery directly? Because some functions in jQuery are unnecessary? Or for easy maintenance?<br>
Thanks in advance!</p>
