Echo JS 0.11.0

I love JS, love node... but "fast" is relative.  There is also scale, and environment cost to consider.  You need a runtime, you may need a convoluted build environment.  It varies.

For me, it's a language that almost everyone has to know/use as so many applications have a web front end.  It's a scripted language that runs almost everywhere you'd want it (Linux, Windows, Mac).  You don't generally need a build step for orchestration scripts.  package.json tasks with npm make it easy to have your dependencies and the task definitions in one convenient spot.
