I use Scala.js too. I haven't been able to set up a working sourcemap with our workflow of Scala.js -> Webpack -> JS. It's difficult to debug the mangled JS output but I can just about do it--barely. By contrast, reading BuckleScript's output JS is a breeze. No name mangling, idiomatic style, sensible code flow.
