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.

Concurrency and Functional Programming

Concurrency is all around us, both in the real world as well as the virtual one. Humans can easily multitask (although we might not do a good job at either task). It’s entirely possible to drink a cup of coffee while you are reading this chapter or to run while listening to a podcast. For machines, concurrency is a complex undertaking, although a lot of that complexity can be hidden away by the programming language we choose.

Go was built to be a language with all the necessary tools a modern-day software engineer needs. As we are now in a world where CPU power is abundant for most intents and purposes, it’s only natural that concurrency was a main concern when developing the language, rather than having to bolt it on later. In this chapter, we are going to take a look at how functional programming can help with concurrency and, conversely, how concurrency can help with functional programming.

In this chapter, we are going...
