Is the ES3 vs. ES5/ES6 comparison valid? The latter were subsequent versions of the former, kind of like Angular 2 vs Angular 1. Whereas Backbone, Ember, React, etc. are all different, each with its own "way" of doing things.

I used ES5/6 because those are (I hope) in the eyes of the HN community clear improvements over ES3. I personally wouldn't use ES5/6 nowadays, and instead use TypeScript or PureScript. Both of which are IMO even bigger improvements. Backwards compatibility does not matter in this comparison, what matters is the relative ordering: Backbone.View < React, ES3 < ES5 < ES6, and IMO: ESx < TypeScript/PureScript.
