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.

Introducing Functional Programming

In this first chapter, we are going to take a bird’s eye view of the what and why behind functional programming (FP). Before we dive into the nitty gritty of FP, we first have to understand what benefit we get from applying these techniques to our code. To start off, we will provide a brief look into the history and contemporary state of FP methodologies. Next, we will take a look at how FP compares to more traditional object-oriented programming (OOP). Finally, we will also discuss the “Go programming paradigm.”

The main things we will cover in this chapter are as follows:

  • What is FP?
  • A brief history of FP
  • A look at the current state of FP
  • A comparison of traditional object-oriented and functional methodologies
  • A discussion on Go programming paradigms and how FP fits into this
