How to use scheme2js and hopc -j

[natethern]

While trying to find out how to use scheme2js I came across this old mailing list thread:
https://www.mail-archive.com/hop@inria.fr/msg00109.html

Now I can compile the example coucou.scm into coucou.js - but I can't figure out how to run coucou.js in a console.

hop.js does not provide the sc_display function and I can't make it work with any of the .js files that do provide sc_display either.
