> More specifically they want to use one language for the front and back end

What I mean here is exactly what I mean. Excuse the tautology because I don't think I can express it any clearer. It was in contrast to this:

> I believe it's pretty clear that htmx (and Phoenix) exist (at least in part) because people specifically _do not_ want to use Javascript.

Taking your example, Phoenix Liveview exists because Elixir developers want to use the same language across the stack. This might be because they are unfamiliar with JS, and learning a new language might be a pain. Or perhaps they are familiar with JS, but the context switch to another language still presents enough friction to avoid it. Choosing a single-language stack doesn't imply an aversion to JS in particular.
