I don't even think the worst part is the download (which can be cached). The worst part is the fact that you're running your script, interpreted by a weirdly generated unoptimized script, interpreted by a scripting engine which only then runs on metal. I'm shooting in the dark, but I'd bet the performance and memory usage would be a disaster for anything but Hello, world.

Actually, right now, even Hello world is a disaster. My guess is that this will drive some interesting improvements to emscripten and LLVM so there may be some benefits down the line.

There's also going to be an enormous startup time as it has to parse and compile all that code, even if it's already cached.
