The Caml Hump: OCamljs

Ocamljs compiles OCaml to Javascript. It uses the standard OCaml front-end, so the full language is supported (the object system is partially supported, should be fixed soon). Included are several libraries for Web programming, as well as a library for working with Javascript via Camlp4. It works with orpc for RPC over HTTP, and with froc for functional reactive browser programming.
