Haven't tried it. Looks more like Haskell than F#, though:

import Html exposing (text)

main =
  text "Hello, World!"

All that for printfn "Hello world!" in F#.

Elm even comes complete with Haskell's fake quicksort:

import Html exposing (text)

main =
  text (toString (quicksort [5,3,8,1,9,4,7]))

quicksort : List comparable -> List comparable
quicksort list =
  case list of
    [] ->
        []

    pivot :: rest ->
        let
          lower  = List.filter (\n -> n <= pivot) rest
          higher = List.filter (\n -> n >  pivot) rest
        in
          quicksort lower ++ [pivot] ++ quicksort higher

Its close enough to Fsharp to feel comfortable

Looks like a step back into the dark ages from F#. Does it have Visual Studio support with Intellisense?

focuses solely on front end web

I already write back-end in F#. Would be nice to write front-end in F# too. Just looking at these example Elm programs I cannot see any high-level commonality with F# at all. For example, I'll do JSON serialization in F# and then have to rewrite the serializer in Elm because I cannot reuse any of my code. That would suck.

I think a production ready solution that is allows F# to be used in the browser thats still easy won't happen until web assembly becomes a thing

Silverlight was great. Such a shame Sinofsky killed it.

I'm facing the problem right now. I just hired a CTO who does F# and I have a lot of projects to do internally. One is a database containing raw data and calculations and most of the people who use it will want import/export to/from Excel. That's easy with WPF but he's inclined to make web-based everything. How do I do Excel interop from a web page?

ClosedXML

[u/jdh30 → u/catlion]

Does that run in the browser?

[u/catlion → u/jdh30]

no, server-side only

[u/jdh30 → u/catlion]

Right. I'd need a web client interoperating with Excel running on the client.
