Thanks Arjen,
but I was hoping to get some more in depth information. The dojo provide and dojo require are clear to me for a single script, but i'm really looking to how for example include several javascript files including JQuery without interference with dojo and preferably setting it up in such a way that both dom.byId("fooBar"); and $ can be used throughout my entire project to target elements. I wish to be able to use JQuery because there are many great scripts created using JQuery and I dont really feel like rewriting every single one of them to a dojo version, so I was hoping including both libraries would be fairly easy.
Loading javascript libraries can be done. An example is given at this post.
