I personally found F# to be a decent alternative to Elm for small browser apps with Fable, Elmish/Feliz, Feliz.Plotly etc. You can generate typed interfaces for any libs you're missing which have a typescript interface using ts2fable, that's the kind of pragmatic tooling you need if you're veering off the well-trodden path in commercial development. Ionide in VSCode is excellent (though not perfect) and the compilation times are decent. In terms of community (which is not unimportant when it's that small) even the compiler gitter folks were super helpful when I had some reflection questions. Overall I'd use it again for small browser apps, for backend I guess it depends on your company and domain.
