It's a general purpose language (as mentioned several times) and compiling to js eg. for lustre webapps (elm-ish). I've contributed to the js compiler once only and can't find a way to use more gleam at my job but I'd say having failsafe actor based erlang backend + ssr + rich strongly typed reactive frontend all in one language is really cool.

It seems your stuck on js-only for ui and somehow rejecting compile to js. If you don't wanna use it fine but I'm not sure what you're looking for in this thread...
