Any good reference on how to do FP in Scala?

[Saxo]

Hi,

just read the article by Martin Odersky about Scala being postfunctional (see link). What he says looks fairly reasonable to me. There is some phrase by Andrey Breslav (creator of Kotlin) I agree with: "FP makes things simpler. Sometimes at a huge price". That's why I like the moderate approach to FP in Scala. Choose OO or FP depending on the situation.

Problem is that I only had a course on Scheme when studying. I don't have any real understanding of FP. If I sit down and try to do some FP in Scala where appropriate it is only something I think it were FP. So what I'm looking for is some reference (article, book, whatever) that explains to an FP novice what would be meaningful way to do FP in Scala.

Thanks a lot for any hints.
Regards, Oliver

How about Martin Odersky's Functional Programming Principles in Scala (https://www.coursera.org/course/progfun) online course, or the book Functional Programming in Scala (http://www.manning.com/bjarnason/)

This looks very good. Thanks. Maybe I'm too much used to searching on Amazon ;-).

There's a book being written by some of the authors of scalaz. I highly recommend it, though it is by far not finished yet.

Also from Manning, Scala in Action (http://www.manning.com/raychaudhuri/) covers a fair amount of FP use in Scala, though I've seen some heavy criticism to it from some of the fp crowd. Still, I can't help but like that book.

From Artima (publisher of PinS), there's Monadic Design Patterns for the Web (http://www.artima.com/shop/monadic_design_patterns). I haven't looked inside it, but I have long been waiting for it to come out.

Not that I don't think Functional Programming in Scala and the coursera course aren't exceptional recommendations -- they are.

I would definitely start with the online course - which will be  permanently available according to what Odersky said at ScalaExchange on Monday. The examples in the course are fantastic - really good for working through step by step.

The book mentioned above is heavier going and would be much better approached after you have some fluency with the language - which the course could bring.

Oh! One more: Scala in Depth (http://www.manning.com/suereth/) also from Manning. With the great advantage of being out already, instead of early access. It's not about functional programming, but it's definitely the book to get if you want to level up your scala programming skills.
