Now how do i learn JASS?

I want to learn JASS and i have read the FAQ but it only learns me a few basics, now how do i do to learn more? Is it true that the only way to be better on JASS is to convert triggers and study them?

Anyways the FAQ was great :infth:

JASS is actually a pretty simple programming language. There is not much to learn. It helps to study blizzard.j and common.ai to learn a bit. In common.j there are all the native functions that are hard coded and can be called to do things. The AI specific natives are in common.ai .

Thanks, I hope to sit down some more and work some more on the FAQ. I plan on adding a part about Variables & Arrays soon. When I can sit down.
Once again glad it helped, I think I will add the url to my sig.
