Echo JS 0.11.0

I really like parcel, in many ways for the same reasons I like jest.  Trying to wire it all up yourself is *so* much effort, that I'm willing to spend a couple seconds on initial builds to account for it.

Similarly, Jest does such a good job at wiring up coverage, which is really a pain with say mocha.

I't a bit more pragmatic, and I still have to do some leg work.  I'll probably start using v2 in the next few months.  I tried an early beta and had some issues with it.
