If you want to go from a 0 understanding of JASS to almost a full of understanding of JASS, you can do what I did and tutorial the whole way for about half a day... First make sure you have a good understanding of how to trigger in GUI, or you have no hope in JASS. If you can't trigger normally (in GUI), look up some tutorials. If you can do normal triggers, you can move on to JASS .
