Echo JS 0.11.0

I'm a fairly technical person and I still don't understand ZestJS after skimming the page.  The only line that rang a bell was "[ZestJS is NOT] A dictated environment - it's more of a tool and a method than a framework." I'm probably not the target audience, but it would be nice if you could lead with what problem this library solves and what the "Aha!" aspect is of this tool.
