Lex Sheehan begins slowly, using easy-to-understand illustrations and working Go code to teach core functional programming (FP) principles such as referential transparency, laziness, recursion, currying, and chaining continuations.This book is a tutorial for programmers looking to learn FP and apply it to write better code. Lex guides readers from basic techniques to advanced topics in a logical, concise, and clear progression.The book is divided into four modules.
The first module explains the functional style of programming: pure functional programming, manipulating collections, and using higher-order functions. In the next module, you will learn FP techniques that you can use to improve your API signatures, increase performance, and build better cloud-native applications.
The last module covers Category Theory, Functors, Monoids, Monads, Type classes and Generics.By the end of the book, you will be adept at building applications the FP way.
