Key Features
- Write concise and maintainable code with streams and high-order functions
- Understand the benefits of currying your Golang functions
- Learn the most effective design patterns for functional programming and learn when to apply each of them
- Build distributed MapReduce solutions using Go
Book Description
Functional programming is a popular programming paradigm that is used to simplify many tasks and will help you write flexible and succinct code. It allows you to decompose your programs into smaller, highly reusable components, without applying conceptual restraints on how the software should be modularized.
This book bridges the language gap for Golang developers by showing you how to create and consume functional constructs in Golang.
The book is divided into four modules. The first module explains the functional style of programming; pure functional programming (FP), manipulating collections, and using high-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, to increase performance, and to build better Cloud-native applications. The last module delves into the underpinnings of FP with an introduction to category theory for software developers to give you a real understanding of what pure functional programming is all about, along with applicable code examples.
By the end of the book, you will be adept at building applications the functional way.
What you will learn
- Learn how to compose reliable applications using high-order functions
- Explore techniques to eliminate side-effects using FP techniques such as currying
- Use first-class functions to implement pure functions
- Understand how to implement a lambda expression in Go
- Compose a working application using the decorator pattern
- Create faster programs using lazy evaluation
- Use Go concurrency constructs to compose a functionality pipeline
- Understand category theory and what it has to do with FP
About the Author
Lex Sheehan has a B.S. in Computer Science from Auburn University, resides in Atlanta, GA, and works as a senior software engineer with over 20 years of experience.

主要特點
- 使用串流和高階函式撰寫簡潔且易於維護的程式碼

書籍描述
函數式程式設計是一種流行的程式設計範式,用於簡化許多任務,並幫助您撰寫靈活且簡潔的程式碼。它允許您將程式分解為更小、高度可重複使用的元件,而不會對軟體的模組化方式施加概念上的限制。
本書通過向您展示如何在 Golang 中創建和使用函數式構造來彌合 Golang 開發者之間的語言差距。
本書分為四個模組。第一個模組解釋了函數式程式設計的風格;純函數式程式設計(FP)、操作集合和使用高階函式。在第二個模組中,您將學習可以用於構建 FP 風格應用程式的設計模式。在下一個模組中,您將學習可以用於改進 API 簽名、提高性能和構建更好的雲原生應用程式的 FP 技術。最後一個模組深入探討了函數式程式設計的基礎,介紹了類別理論,以便軟體開發人員真正了解純函數式程式設計的內涵,並提供適用的程式碼範例。
通過閱讀本書,您將能夠以函數式的方式構建應用程式。
您將學到什麼
- 學習如何使用高階函式組合可靠的應用程式
