I'm not aware of anyone working on it. There were some attempts with Emscripten which ran in to unsupported instructions; some of those may be supported by newer versions of Emscripten, but I haven't heard of any attempts to get this going recently.

Gotcha. Is it definitely technically feasible, or is that still unknown?

[ihnorton]

For Julia core it should be feasible, but possibly requiring patches to Emscripten, so the level of effort is still unknown. The other issue is the C and Fortran numerical libraries -- some of which use inline-assembly, others (Fortran) don't have a working LLVM frontend as far as I know.
