It allows you to decompose your programs into smaller, highly reusable components, without applying conceptual restraints on how the software should be modularized.\u003c\/p\u003e\u003cp\u003eThis book bridges the language gap for Golang developers by showing you how to create and consume functional constructs in Golang.\u003c\/p\u003e\u003cp\u003eThe book is divided into four modules. The first module explains the functional style of programming; pure functional programming (FP), manipulating collections, and using high-order functions. In the second module, you will learn design patterns that you can use to build FP-style applications. In the next module, you will learn FP techniques that you can use to improve your API signatures, to increase performance, and to build better Cloud-native applications. The last module delves into the underpinnings of FP with an introduction to category theory for software developers to give you a real understanding of what pure functional programming is all about, along with applicable code examples.\u003c\/p\u003e\u003cp\u003eBy the end of the book, you will be adept at building applications the functional way.\u003c\/p\u003eStyle and approach\u003cp\u003eThis book takes a pragmatic approach and shows you techniques to write better functional constructs in Golang. We'll also show you how use these concepts to build robust and testable apps.\u003c\/p\u003e","brand":"Packt Publishing","offers":[{"title":"Default Title","offer_id":47114699669744,"sku":"9781787286047","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781787286047_p0.jpg?v=1763740938","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781787286047","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
