I did try F#, but I was new to .NET ecosystem. For 1 "hello world" I was quite surprised by how many project files and boilerplate was generated by .NET, which put me off. I am all for FP, immutable, and modern languages. But then where are the jobs and which companies care if you write good code? Now everyone wants languages which are easy to use with AI, while reducing workforce and "increased productivity". I have…

I understand your perspective. I like to view niche languages as a medium for learning. For instance, I enjoy using Rust in my personal projects—even if many of these projects may never be released—because the lessons on immutability, functional programming constructs, and trait-oriented programming significantly enhance my day-to-day work. Therefore, I believe that learning niche languages, even in the absence of a…

I'm not sure I'd call Rust a "niche language" any more (perhaps in ~2018) - it's in common use across many big technology companies.

I have a few questions. Can it do GUIs well? How about mobile? And how does it compare to e.g. Scala?

Sprinkle some HTMX next to your favorite template engine and you're g2g

Which is what I am doing with my personal website for the most part. Elmish for the subpages where a lot of interactivity is actually needed. Otherwise just using Feliz.ViewEngine with htmx purely for enhancements

The problem with F#, Clojure and Elixir (hosted languages) For F# , you need some basic C# knowledge For Clojure, you need some basic Java knowledge For Elixir, you need some basic Erlang knowledge I like all 3 languages but usually each vm have a primary language, and each hosted language eventually become hosted on that primary language not the vm I understand that for many task simple, to medium complexity, you mi…

Erlang is not a difficult language. Unusual, but actually quite sane syntax. If you are already familiar with Elixir it would probably be pretty easy to learn the basics of Erlang.

> For Elixir, you need some basic Erlang knowledge As an Elixir programmer, this does not resonate. Basically the only thing I've ever felt I needed to understand Erlang for was ets, but let's be honest, that's not really proper Erlang but just the terrible ets query syntax. And all this requires is "ability to read enough erlang term syntax to be able to understand the ets manual". I don't think I could write a sing…

Thanks. I know a bit of Erlang (put some effort into learning, but never used it in real life, probably forgotten what I learned) and want to learn Elixir which seems better suited to what I want to do in the short to medium term.

Earlier quoted context omitted.

The funny thing is that you can write very similar code in C#, so maybe you don't need to switch which language you're using as a CLR frontend. using System.Linq; using System; var names = new string[] {"Peter", "Julia", "Xi" }; names.Select(name => $"Hello, {name}").ToList().ForEach(greeting => Console.WriteLine($"{greeting}! Enjoy your C#")); LINQ is such a good library that I miss it in other languages. The Java s…

This isn’t a great example of what linq is good at. There’s no reason to do ToList there, and the ForEach isn’t particularly idiomatic

Yeah, I hit the problem that there isn't a null-type equivalent of Select() for Action, nor is there a IEnumerable.ForEach (controversial), so that's a bit of a hack. But I wanted to make it as close to the original example as possible.

As far as I can tell F# is one of those things where every single user is extremely happy. This happens rarely and I really am curious about the thing but never had time to get into it. I'm also pretty well versed in the .net ecosystem so it's probably gonna be easy. Any tips? What kind of workflows might benefit the most if I were to incorporate it (to learn..)?

I love LINQ, maybe a little too much. I can end up writing monster oneliners to manipulate data in just the right way. I love list comprehensions in python too, since they can work in similar ways

I tried F# some years back when I was searching for a language to port my OCaml project in... It felt too much .NET-y and too much MicroSoft-y. And back then .net for linux had just been released and was somewhat unpolished.

It seemed that I had to learn C# in order to use F# properly and it seemed that porting it to C# was the saner option. I went with Rust after all and it seems to have been the right choice.

Because you love using Microsoft's shitty technologies, but also want to be completely unemployable?

I've spent my entire career, 22 years, primarily in C#. I'm quite employable.

If we go by the joke in gp, this is you.

Coming from a .NET developer - why NOT F#?

* Network effect, or lack thereof. Very few people use it. * Its nature is contrary to the ecosystem. The CLR is fundamentally resistant to the paradigms that F# creates.

Wonderful little language - one of my favorites - and we owe a lot to it for the great features that C# has. But it just hasn't picked up the critical mass it needs.

It is possible to start your project with the script possibilities offered by F# (as mentioned in the blog post). It is absolutely a viable approach and I even blogged about it a couple of months ago: https://www.asfaload.com/blog/fsharp-fsx-starting-point/
