Learning Functional Programming in Go: Change the way you approach your applications using functional programming in Go | 248 | Lex Sheehan | 2017 | Packt Publishing |

Function literals, Monads, Lazy evaluation, Currying, and more 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 pure functional programming, manipulating collections, and using higher-order functions. In the second module, you will learn design patterns that you can use to build FP-style applications. 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. This book is for Golang developers comfortable with OOP and interested in learning how to apply the functional paradigm to create robust and testable apps. Prior programming experience with Go would be helpful, but not mandatory.
Leverage core functional programming (FP) concepts to write more maintainable and testable code in Go

Key Features
• Learn functional programming techniques at the architectural level and use them to solve real-world problems
• Understand how to think about code functionally
• Learn about the trade-offs of functional programming and object-oriented programming (OOP) in Go

Book Description
While Go is a multi-paradigm language that gives you the option to choose whichever paradigm works best for the particular problem you aim to solve, it supports features that enable you to apply functional principles in your code. In this book, you'll learn about concepts central to the functional programming paradigm and how and when to apply functional programming techniques in Go.

Starting with the basic concepts of functional programming, this Golang book will help you develop a deeper understanding of first-class functions. In the subsequent chapters, you'll gain a more comprehensive view of the techniques and methods used in functional languages, such as function currying, partial application, and higher-order functions. You'll then be able to apply functional design patterns for solving common programming challenges and explore how to apply concurrency mechanisms to functional programming.

By the end of this book, you'll be ready to improve your code bases by applying functional programming techniques in Go to write cleaner, safer, and bug-free code.

What you will learn
• Gain a deeper understanding of functional programming through practical examples
• Build a solid foundation in core FP concepts and see how they apply to Go code
• Discover how FP can improve the testability of your code base
• Apply functional design patterns for problem solving
• Understand when to choose and not choose FP concepts
• Discover the benefits of functional programming when dealing with concurrent code

Who this book is for
If you are a Go engineer with a background in traditionally object-oriented languages such as Java or C++ and want to broaden your knowledge of functional programming, this book is for you.
