Echo JS 0.11.0

The article title is somewhat misleading... "ECMAScript Proposals That Didn't Make It In 2017" would be more accurate... realistically, most of these will likely make it by end of 2018 for whenever the ES2019 cutoff happens.

Absolutely right. That's exactly what we meant (and why we changed the title), but you're not the first to point that we could have been clearer. Our bad.
