Functional Programming in Go

By: Dylan Meeus

Overview of this book

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.

To get the most out of this book

Prior to picking up this book, the reader should be familiar with Go and generics. The basic concepts of the programming language (control flow, structs, and imports), how to build and run applications, and how to import open source libraries from GitHub should also be understood by the reader.

Software/hardware covered in the book

Operating system requirements

Go (pre- and post-generics)

Windows, macOS, or Linux

Having Go 1.18 or later installed is a prerequisite for the majority of this book. Certain chapters will also work on Go version’s prior to 1.18, this will be called out per chapter. Most of the code will also work in the Go playground at https://go.dev/play/.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book’s GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.

Some chapters will have snippets in Haskell and Java for illustrative purposes of (pure) functional and object-oriented counterparts to Go.
