Article is a total tour de force. The OP has contributed so much to the Scala community; somehow he's a Python + Coffeescript developer by day, and an absurdly prolific Scala library author in the evenings. As for Scala.js, representing browser interactions in types is such a relief, and to have the entire Scala language available is almost too good to be true: client-server interop is seamless. Really the only negative for me is the Scala collections library. Of the @100KB Hello World[1] generated blob half of that is Scala collections. There's a small initial "tax" to pay basically, and thereafter size increase is on par with normal javascript. [1] not totally true, vanilla Hello World is more like 40KB, but once you define a Scala collection then generated blob doubles in size.
