In my SP2013 environment, I use jquery, but had the issue of the $ clashing with Sharepoint's own $. The original thread was here
In there, this link was brought up
which introduces SharePoints own mQuery. So now I am wondering, for long term use, is it better to switch to mquery completely and get rid of jquery? Or just continue to use jquery. Because if I use mquery, then its dependant on SharePoint mquery version which may change in future versions like SP2016 or the next version. This would break code, or worse, they could drop mQuery for something better (from themselves or some other company). They did this with Full Text Query, and said switch to KQL.
However if I stay with jquery, then even if they change, I can always keep using the jquery version file that worked. So it seems like jQuery is more stable in terms of long term usage.
Does anyone have any advice for this issue?
