Hi @amasad, In collaboration with @jpolitz, we've been working on way to debug programs written in arbitrary source languages in the browser that you may find interesting. You can find a technology demo here: http://www.stopify.org http://www.stopify.org Stopify uses existing compilers that produce JavaScript (e.g., ScalaJS, BuckleScript, etc.) We've tested with ten languages, five of which are on the website. There are three key pieces to Stopify: (1) first-class continuations for JavaScript (warts included), (2) browser-specific optimizations, and (3) language-specific optimizations (i.e., many compilers emit a sane subset of JavaScript that Stopify can exploit to improve performance). We've conducted a pretty extensive performance evaluation that we can also share. E.g., we've found that PyJs + Stopify can be as fast as Skulpt with suspensions.
