Was really tired, so I was going to go to bed ... as soon as I finish this video.

So I’ve just watched almost two hours of videos about # (and #, but the interesting part of Opa is Ocaml, rather than the JavaScript part). https://ocaml.org/

Going to bed now. #

BTW: MLState, the company behind Opa, was purchased by Wallix 2-3 years ago. It appears that Opa development halted at that time. https://github.com/MLstate/opalang
