> It's perfect if you've got a great big POSIX C + SDL codebase that you want to run in its own self-contained environment in a browser, but it's not very helpful for writing idiomatic Javascript code that just needs to drop into optimised asm.js occasionally for some heavy lifting. That's not really true -- it's pretty easy to call into an Emscripten module from javascript. You have to do some data marshalling, but that's true of any dynamic language -> c binding.
