I can do this - PS C:\foo> dotnet --version 1.0.0-rc4-004771 PS C:\foo> dotnet new mvc -lang F# Pretty certain this is 4.1 and already out. Articles have been around for a while https://medium.com/real-world-fsharp/using-f-with-net-core-a...

Fsharp 4.1 does not appear to be released yet. The download for windows is still 4.0. Last I looked ionide did not support .net core. I'm betting it will be released as part of the VS 2017 visualfsharp update. They just called for help testing RC3. I'm looking forward to the release and the subsequent smoothing of the .net core fhsarp ecosystem.

Ok, yeah, influenced. Javascript could also be called a LISP with C-Syntax, but that wouldn't make it a LISP. But I get what you mean.

You should compare the actual syntax and constructs. I agree that JS and LISP certainly are as far apart as anything else, and Python is as "functional" as any other imperative language. But Scala indeed is very similar to (1) OCaml and then (2) ML, and last, (3) Haskell in terms of type inference, syntax, and many other FP concepts [1]. [1] http://www.appservgrid.com/hyper/hyp/ml

Scala is Hindley-Milner?

I had looked at Frege, but it doesn't seem to have the same traction as other functional languages. Counting on github returns about 10k for each F# and Ocaml, about 60k for Haskell, and 100k for Scala, but about < 200 for Frege.

I've recently got back in to F#, one thing I like is the fact you can leverage the world of .NET For instance, first thing I did was I used suave.io to expose a webservice for a digital IO module ( http://www.mccdaq.com/ ) and it amounted to around 50 ish lines of code. Runs flawlessly. The F# community is pretty awesome as well with a good ratio between experts and people learning the language.

fsharp would really take off if it had a framework as attractive as phoenix.
