>A spotty connection hasn’t loaded the dependencies correctly - Either they load or they don't. How would the dependencies load "incorrectly"?

Let‘s say you have 5-7 dependencies to load, but 3 of them timed out because your train entered the tunnel. Your app ends up in incorrect state, fails silently and UX degrades unpredictably. This is where the conversion often drops visibly and the reason SSR is now a go-to solution for any marketing website.

Don't worry, it's only in the HN bubble that adding a 500ms round trip to open a damn menu is acceptable and commended.

> I'm just tired of being downvoted every single time I mention that JavaScript is necessary on the modern web

Downvotes should give you a hint that the few users that know what javascript is, don't like it, and the rest of them, if they learned, most likely won't like it either. Your attitude shows that you don't care.
