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

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.

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.
