"Functional Programming with Go" is a comprehensive guide to introduce Go developers to the powerful concepts of functional programming. This book covers topics like first-class functions, closures, higher-order functions, immutability, and pure functions. It also demonstrates how these principles can enhance code quality, reliability, and maintainability. Starting with functional programming basics and setup, it covers first-class functions, closures, and higher-order functions like map, filter, and reduce. You will learn advanced techniques like currying, immutability, and functional error handling with monads. The book also explores concurrent programming with FP in Go, design patterns, functional web development, testing, debugging, and advanced topics like memoization. This book equips you with the knowledge and skills needed to write efficient, scalable, and robust Go applications. By the end of this book, you will have the knowledge and skills to apply functional programming principles in Go.
