What are the pro’s and con’s of each. How do the communities compare.

Random things not mentioned above: F# has units of measure ( @gasche mentioned it, but adding a link) F# does not have named arguments (in normal functions), which I am reminded of constantly when I use it The type inferencing in F# isn’t quite as good, but can’t put my finger on why. I have to ann…

F# does runtime monomorphisation whereas OCaml uses an uniform representation through pointer-tagging on a single machine word. Thus in F# you can easily observe the JIT causing pause time in the execution. E.g. if you implement Okasaki’s random access lists: type ral<'a> = | Nil | Zero of ral<'…

Still no good comparison between the two is lacking. [Whereas comparison to rust or scala is available ]

What are you looking for? Can you share the rust vs scala comparison you’re referring to? There’s many good comments here explaining a lot of good differences.

@mro Received mine! Thanks alot. It came as a surprise haha

There are alot of communalities. If you know one you know the other. One small difference on syntax are: -Ocaml uses keyword “in” and “;” operator , whereas F# uses indentation and spaces. -F# uses <> around type types.

ocaml has a nice binding to the tk library to make a gui. F# has not.

F# history is perfectly captured in The Early History of F# and how it relates to ML family of languages. There are missing / added language features on both sides, I missed the module system the most in F#. On the practical side, I found developing F# to be quite foreign as a life long Unix perso…
