Key benefits

Learn functional programming techniques at the architectural level and use them to solve real-world problems

Understand how to think about code functionally

Learn about the trade-offs of functional programming and object-oriented programming (OOP) in Go

Description

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.

What you will learn

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

I recently read ‘Functional Programming in Go’ and found it to be a great resource. The examples were particularly well-explained and easy to understand. The techniques explained in the book about functional programming were very helpful. I would highly recommend this book to anyone looking to learn more about functional programming in Go.

It's a good introductory book to functional programming in Go.Highly recommended

Sai teja mesala Mar 31, 2023

This book offers a comprehensive package for understanding functional programming in Go. The author provides detailed explanations of functional patterns and their appropriate usage, including when to use them, how to use them, and when not to use them. The author's use of code standouts is especially helpful in illustrating the concepts. By the end of the book, readers will have a better understanding of how built-in Go functions work, such as sort.Slice. I had the opportunity to read a copy and am grateful for that. Overall, I would say that this book is most suitable for entry-level to intermediate-level Go developers.

Amazon Customer May 04, 2023

This book is a really well laid-out, entertaining, insightful read into what functional programming (FP) is - and is not - and how Go can apply the ideas. The examples are simple, iterative, practical and useful. The chapters aren't overly wordy with theory, and the writing is VERY good. I'd recommend this as essential reading for Go developers of any level, as the application of the ideas will make you not only a better programmer, but more equipped to solve problems in a scalable way. Great work!

As a software engineer who has only really dabbled in Go and in Functional Programming with Haskell, this has opened my eyes to a lot of the power that lies behind the 2.Firstly the introduction to the book is rife with information about what to expect going forwards. It lays out the chapters and what will be covered in each one, as well as providing a GitHub with examples to follow. It walks you through getting setup and places you in a position where you can easily follow along, try out the examples further on in the book and get a real feeling for the power behind Go and writing Functional code within it.One thing I really enjoyed about this book is the emphasis on using the right tool for the job. The author stresses that whilst Functional Programming is a great paradigm (similarly with things like Pure functions over Impure functions), it's not ALWAYS the right way to go, an they go into why that is, and when to use each.If you're an engineer from other, more predominantly OOP, languages such as C# or Java, you might find certain elements of this book familiar. That really helps to understand what is going on at each step along the way; a lot of the examples in this book will be easy to relate to and understand as a result of this.The author talks about function purity, recursion, currying, higher order functions, testing, functors & monads, function categories (alongside some examples you could apply to the real world), function composition, functional design patterns, concurrency and WAY more. Examples are provided for every step and are ideal for the given topic, thus easy to follow and understand as well as relate to.I've come away from this book with a far greater understanding of both Go and the Functional paradigm itself, in fact I now want to go away and explore how I can utilise the Functional paradigm in other languages I enjoy using, just because!It's not a fast read, you'll want to play around with your own version of each example and tinker with things; I personally think that's part of the beauty of this book.The contrast between OOP and FP is made clear in this book; you can really see the pros and cons of both and apply those to your daily work.For any of you out there who struggle to wrap your heads around Monads, this book gives a fantastic description by walking you towards it over time rather than dropping the concept on your head and expecting you to understand it. I really enjoyed that, and this made me realise I hadn't quite got it right up until now!This book really does delve into the specifics and advanced side of things, but you're taken on a journey to get there with a more full understanding of things. Don't be put off by scanning the Table of Contents and seeing some complicated topics on there, as by the time you reach them you'll know everything you need to know.In summation I'd advise this book to anybody with a remote interest in Go and / or Functional Programming. If you're curious about either and haven't used them much this book will give you an understanding of them and you'll know by the end whether you want to play with them or not. In most cases I imagine you will want try both out, but in particular Functional Programming as it's a fantastic paradigm to get wrapped up in.Give this a read and prepare to lose hours in the examples, it's a fun journey and you won't regret it.
