Don,

I know it's not the full answer but I note Annex E in the new specification : Additions and Changes That Introduce Incompatibilities with Prior Editions
http://www.ecma-international.org/ecma-262/6.0/index.html#sec-additions-and-changes-that-introduce-incompatibilities-with-prior-editions

Subject: [x3d] Standard ECMA-262 for ECMAScript (JavaScript) updated to version 6, June 2015

The ECMAScript (JavaScript) standard has been updated:

	http://www.ecma-international.org/publications/standards/Ecma-262.htm

The X3D language binding for ECMAScript ISO/IEC CD 19777-1:201x V3.3 specifies how Script nodes in an X3D scene interact with JavaScript.

Not finding a differences (diff) list between 5.1 and v6, might anyone know where that is?

The Wikipedia page has a summary of versions and language overview.  Excerpt follows.

	https://en.wikipedia.org/wiki/ECMAScript

"The Sixth Edition adds significant new syntax for writing complex applications, including classes and modules, but defines them semantically in the same terms as ECMAScript 5 strict mode. Other new features include iterators and for/of loops, Python-style generators and generator expressions, arrow functions, binary data, collections (maps, sets and weak maps), and proxies (metaprogramming for virtual objects and wrappers). As the first “ECMAScript Harmony” specification, it is also known as “ES6 Harmony”."

If anyone has comments for the X3D working group about upgrading our current ECMAScript reference (Version 5.1 from June 2011) they will be welcome.

all the best, Don
