Book

I have written a book that teaches practical functional programming starting with basic fundamental topics and ending with concurrent programs that use streaming concepts and lots of I/O: “Grokking Functional Programming”.

Code repository

The book comes with a self-sustaining code repository. Go ahead and check it out on GitHub @ https://github.com/miciek/grokkingfp-examples and read the README.md there to learn how the code repository should be used with the book.
