Thanks so much for the informative reply: that's a lot of things I don't know about!

This in particular would be great to read about!

I'm less willing to say caveat emptor here, sounds harrier, but again "doing it and creating potential problems" (particularly if they're exit case problems) seems preferable to not doing it. > It would be interesting to delve into these problems, but for example if > you use rust the runtime has explicit knowledge of threads rather than v8 > so you can reduce most of the problems with concurrency to message passing > and the same problems as process.* People who complain about threads generally do not have in depth knowledge > of difficulties in doing so with Node's environment, but should feel free > to look them up and discuss solutions rather than simply stating "it should > have threads". I have done some attempts at research on the topic: this has been considerably more informative than any threads I've turned up. Perhaps I was doing my search wrong. That all said, apologies for not being able to bring a more balanced perspective to my "should have threads" stance, I would like to be able to do better. > personally really like what Threads a Go Go does, but it still faces the > difficulties listed above difficulties when you start to delve deep into it.
