@julian: Yes, it depends. In the case of NodeBB they must have been quite good lines from what I've seen, and with excellent speed and performance. Thanks for your good work.
I like NodeBB's source, though it would be nice to have real documentation for it 😉 Maybe even something like consistent JSDoc comments?
Thank you for the kind words, by the way. I'll keep updating this post from time to time 😊
