As mentioned upthread, hello world isn't really representative. A more useful metric is probably what I'm doing -- a large, complex single-page business app with lots of specialized gadgetry.

Including the standard Scala.js prelude (100-200k), that currently clocks in at a bit under a megabyte. That's quite reasonable for a program of its complexity, and loads pretty fast. And once that is loaded and in the browser cache, the UI is lightning fast afterwards...

Thanks for the perspective. It seems like a viable option for the frontend of my planned product, which I hope to write in Scala + Play.
