I have been writing F# professionally for over a year, including one relatively large project. I like the pragmatic approach it takes to functional programming. I also enjoy working with other similar languages such as OCaml, Elm and Haskell.
I'm learning F# as my first functional language, coming from c#, and want to get the most from the functional paradigm. Reflecting on mine and others code is a great way to master this very powerful language and programming style.
