Thank you so much for answering my question quickly, I really appreciate it :)
So, you think I should stick to the Mendix learning paths, finish them, then try to work on real life projects (through training or internship, for instance). And only when the need arises, I should consider learning Java Script, right?
I'm quite curious about that because I'm not working at the moment, and I have all the time to learn. I simply want to know what it takes to excel in Mendix.
