I will not add any code in here. Just working on a project and not only this time, but frequently one javascript file kills the others, so I ussually in this situation looked for similar solution (lets say a different slider and etc.)
But are there any more ways to wrap up some how a javascript file that it wont interfere with the others?
If I understood your question correctly, your solution is namespaces.
Usage:
DOM tree:
And you should define you namespace in beginning of each file using
APP.namespace()
