It’s funny you mention HN. With comments and voting and no js.

How do you think HN handles voting and collapsing threads without a page load?
It's this JavaScript that is loaded at the bottom of every page:

There is a no-JS fallback. If you disable JS with uBlock Origin or whatever, then reload the page and try voting, you will see the page reload. But thread collapsing won't work at all.
I think a lot of these "you don't need JS" things you see out there are either (a) a sensible reminder that your JS-filled app doesn't have to do EVERYTHING with JavaScript (looking at you, JSS), (b) a contrarian "JS sucks" take, (c) an appeal to use outdated tech like PHP instead, or (d) just a clever way of getting attention on sites like hackernews.
