Functional Programming Ideas for the Curious Kotliner


About the Book

Kotlin lies in a really interesting intersection of programming styles, with functional programming becoming increasingly popular. Functional style is by no means new, so why not take advantage of the decades of ideas, concepts, and patterns from that community? In this book we explore those ideas with a higher impact on Kotlin code, including how to model data in immutable fashion, describing dependencies using contexts and effects, or treating actions as data.
