Cool, and very thorough! I'll repost if I can think of any questions.

I like it! Formalizing the idea of a reversible iterator, so we don't always have to collect into a list and reverse that, is a great idea.

Formalizing the idea of a reversible iterator, so we don't always have to collect into a list and reverse that, is a great idea. ~TJ
I’m working on a spec proposal that I’d like to present as a strawman (stage 0) for reverse iteration.
leebyron/ecmascript-reverse-iterator
The TL;DR is adding a new well known symbol
Symbol.reverseIteratorand adding methods to the collection prototypes that can be efficiently iterated in reverse. It also suggests addingreverse()to %IteratorPrototype% as an API sugar.I’m looking for broad feedback as well as stakeholders if this functionality is important to you.
