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.

Classical design patterns in a functional paradigm

Anyone who has programmed in an object-oriented language will encounter design patterns at some point. Design patterns are a type of cookie-cutter solution to common engineering problems. One key point is that the solution they provide should be thought of as a starting point, a way to tackle a problem that has proven itself to be useful. Often, the solution is not readily usable out of the box and needs to be adapted to your concrete environment and situation. A given design pattern might provide 90% of a solution to a problem, and the remaining 10% is filled in with custom, non-pattern code.

This chapter does not aim to exhaustively cover design patterns. In fact, entire books have been written about design patterns, such as the well-known Gang of Four book, Design Patterns: Elements of Reusable Object-Oriented Software. What this chapter does aim to do is to showcase how certain object-oriented design patterns translate to the...
