This is my fault, in a sense. In order to get the new Stan compiler (written in OCaml) distributed via CRAN (which requires everything to be built from source on its antiquated build servers), we decided to use js_of_ocaml to translate the OCaml compiler into javascript. See this thread for more details: https://discourse.mc-stan.org/t/a-javascript-stanc3/11044

When I posted that, I didn't really think we would end up using it.

Thanks for this. It's great to get some more perspective on changes ^_^
