JavaScript is the only language browsers will run. It's not gatekeeping to suggest that you have to learn and use JavaScript frameworks if you want to build web applications- it's a fact.
I've had great success with an LV app with minimal JS. The rendering is all server-side in Elixir, plus a few lines of JS hooks for the bits that truly need to happen on the client for a good experience: TZ conversion, countdown timer, table sorting, Chart.js rendering. No framework needed.
The user doesn't notice if a transition takes 100ms because LiveView is fetching an HTML diff from the backend, or 100ms because React is doing an AJAX query to a JSON API, it's the same end result.
