This is a really nice project, and personally is a humorous full-circle:

When I first started moving away from Java web apps (where I hated JavaScript), I fell in love with Scala and it's mix of functional and OOP. Features like Futures/Promises, closures, awesome collection library, etc were so refreshing from Java at the time. After a year or so though, I realized JavaScript offered almost the exact same functionality, and had nice libs like underscore.js for collections, etc. :-)

I've been basically 100% JS for the past 4 years, but still admire Scala.
