If I want to learn about javascript or tools made with it, there are reams of documents and tutorials. They are almost all node based.
But if I want to use JS in TW, I'm reduced to maybe two paragraphs of explanatory material. The only documentation I ever found was by (?) Chris Hunt, which pages have now disappeared except on archive. The code examples no longer match existing core. Trying to clone existing code and hoping that you guess right is like building a ship in a bottle. In the dark. After 5 years, it would really be great to have a bit of documentation for those of us who understand JS but need some hand-holding for the TW-JS gap.
