Discussion on: Do the SOLID principles apply to Functional Programming?

Hey Kasey, thanks for writing this. I heard that about learning functional programming many times, unfortunately for me I still haven't found a way of letting go of everything related to oop, probably with time the functional side will get better. Right now I am in that case you describe. I already watched that talk from Scott is super good though I haven't got into F# yet.

Thanks for the comment. You can retain all your OO knowedge while learning FP, but maybe just put it in a box to the side. :) It is helpful to look at it as going back to basics. You just have data structures and functions, maybe like Go. That is a good starting place for the journey. I wrote an introductory article here. It is for F#, but the principles should apply to OCaml, Haskell, or Reason.

From my experience, really the only way in is learning-by-doing, and best using a language that simply doesn't allow you (or makes it uncomfortable for you) to fall back into OOP thinking. For me that language was Clojure, for some it is Haskell or F#. I never used or looked at F#, but I heard good about it, too. I think learning one of these three and applying them in a real-world scenario will just ease you into FP as a "byproduct".

Thanks for the comments, I agree with everything you said. I also like the approach of learning with a language that doesn't let you fall back. I am also learning with Clojure. I tried Haskell but it was too much for me. So far Clojure has been a very pleasant experience but I still have a long way to go. I am still with the basics. I am using a book called "Functional programming for the object oriented programmer" by Brian Marick, is quite good
