I feel some of this.<p>I almost had a Microsoft-first shop let me use Haskell when I pointed out how many of Haskell&#x27;s lead developers worked at Microsoft Research UK.<p>As for the Microsoft &quot;first party&quot; F# equivalent for the web, that would be Typescript. Typescript&#x27;s typing isn&#x27;t yet to the rigor of OCaml, much less Haskell or Elm, but it&#x27;s getting better every release.
