Thank you very much for your answer. My question was more about the specificity of the training. Front End - Back End. I have never done any code and I would like to be sure not to go in the wrong direction.
I'm not sure what you mean by specificity? Any basic JS training will be helpful if you are starting from scratch.

Yes I know this guy. This is exactly what I want to learn to do!
Thanks a lot for the advice !!

UXP is not available for Illustrator.
UXP is not available for Illustrator yet, coming soon hopefully.
