The performance characteristics are similar are they not?

In the context of the original comment, aren't the performance characteristics of .NET pretty similar to the JVM (though I have no experience with the former)? I don't see big reasons why someone who likes C# would hate Kotlin. F# is pretty different from the available JVM languages though.

  The startup time of .NET is nothing like JVM's in my experience.

    A .Net terminal "hello world" takes a good 2 or 3 seconds on my computer. Yay... :-/

      How fast is it the second time?

      You must be running an old version of .NET or running a computer from 2007. I just created Hello World with .NET Core 3.1 on my 2014 iMac and it's instantaneous first time and subsequent.

  I would say that Scala on the JVM is comparable to F#.

    Only to an untrained eye. F# is a firmly rooted in ML language family history, only making concessions where necessary due to the fact it's running on the CLR. Scala is a random walk of language design space, with different ideas either working or ending up complete trainwrecks, and the fact it's missing this clean ML core makes it a painful language to pick up coming in from F# (or in fact most other statically typed FP languages).

      I mean, considering that Scala has a much more powerful type system than F# and you can actually implement FP concepts like monads, functors, etc makes it arguably more FP than F#. While I haven't used F# much, as a professional OCaml and Scala dev, Scala is hands down the more powerful language. OCaml isn't bad, but it leaves a lot to be desired. A little offtopic, but if OCaml got rid of its module system, added type classes, polymorphic functions, higher-kinded types, multi-core support and removed objects (not that it matters that much), it would be my dream language. Basically, I want Haskell without the dogma. Though, I guess that's what unsafePerformIO provides!

        Why do you say you cannot implement monads and functors in F#? sorry but this is bullshit
        smabie 6y ago
        F# doesn't support higher-kinded types.
        siwatanejo 6y ago
        That doesn't make functors and monads impossible to implement.

And the limitations too. If something (for example, unsigned numbers) is not provided by the JVM because it was declared useless for Java, most languages running over the JVM won't implement it either (and otherwise it would often mean resorting to a layer of more or less dirty and slow workarounds to circumvent the limitation).
