This is a great idea and one I have been asking for for awhile and I am glad GP has implemented this. It will be a big help to us non-advanced users.

I think what we have is enough for curious users with programming skills. Doing something more polished would need to put really too much time. But, you are at the right place to ask question regarding GPScript. I think the best way to learn GPScript is to read the documentation at least once and to start with some kind of small scripting project. Then you can “study” some more advanced collected by @npudar. I also started by trying things and asking other users from the GP community forum.

It’s accessible from the Help menu of course but here’s the direct link

(BTW, I found this thread VERY helpful, as a GP Script beginner with years of semi-pro scripting experience [i.e., ‘wrote many required, but non-pro scripts for my day job’])
