Echo JS 0.11.0

I'm pretty sure ES2019 already cut.  A lot of the features being discussed in the article are not Stage 4 (final).

One of the features mentioned (pipeline operator) is actually something I really think could be great, but there are some competing versions, and no idea which is leading.  I can't help but feel it may be held up for some time, similar to decorators.

Here's a list of what was actually added for ES2019.

There are no "potential" es2019 features... it's already cut... this is a list of the actual features added for ES2019.
