rescript build -w is deprecated
We need to mention it's now rescript watch
Somewhere in this guide, we should mention that people need to bump to latest @rescript/react as it still uses old pipe (|>) syntax.
Concerning pipe-last: V11 formats it away, but only in uncurried mode. Which is another prerequisite for v12 anyways.
@fhammerschmidt sorry for pushing to this branch, I hope I didn't mess anything local up on your end. I've added some stuff I think we need to include. No strong opinion on the exact format, adding the info was my main goal.
It's fine. In fact we could and should crowdsource more articles.
