I have read 10 pages in "javascript: Novice to Ninja" by
Darren Jones. So far it was very good. The pages I read were
at the start when he writes about the history of JavaScript.
Those are just short sections with only short reviews, but
those reviews included exactly all the crucial information -
nothing more and nothing less.

His text also reminded me of the ECMAScript publication mode:
A new version is to appear eavery /June/. So we should have
ECMAScript 2019 by now? Indeed.

Some of the features that were expected for it: »catch {«,
become a superset of JSON, modified Function.prototype.toString,
Object.fromEntries to create an object from an array,
trimStart(), trimEnd(), Array.prototype.flat,
Array.prototype.flatMap, and more.

In which way were editions of ECMAScript from and including ECMAScript Ed. 3
prior to ECMAScript 2019 (Ed. 10) not a superset of JSON already?

How?

Says ECMA :
"ECMAScript 2016 was the first ECMAScript edition released under Ecma
TC39's new yearly release cadence and open development process."
