I am a php developer and relatively new to javascript. But I am doing both front and backend for a project and having an issue with a jquery slider which, when inserted, is breaking 2 other js scripts in the page, including my main menu.

Can anyone point me to a resource that outlines best practices for working with more than one js library and/or raw js ... ???

I'm doing some tests on the order of the scripts right now, but wanted to put a feeler out there to see if someone has dealt with this before.
