Quick Functional Programming
Why learn functional programming? Isn’t that some complicated ivory-tower technique used only in obscure languages like Haskell? In fact, functional programming is actually very simple. It’s also very powerful, as Haskell demonstrates by throwing away all the conventional programming tools and using only functional programming features. But it doesn’t have to be done that way. Functional programming is a power tool that you can use in addition to all your usual tools, to whatever extent your current mainstream language supports it. Most languages have at least basic support. In this book we use Python and Java and, as a bonus, Scala. If you prefer another language, there will be minor differences in syntax, but the concepts are the same. Give functional programming a try. You may be surprised how much a single power tool can help you in your day-to-day programming.
C# Functional Programming Made Easy: A Practical Guide with Examples
"C# Functional Programming Made Easy: A Practical Guide with Examples" offers a comprehensive introduction to the integration of functional programming paradigms within the C# programming environment. Designed for software developers and computer science enthusiasts, this book meticulously covers the origins, evolution, and foundational concepts of functional programming, including the principles of immutability and pure functions. Through detailed exploration, readers will develop a deep understanding of key functional constructs and how C# supports these paradigms through features such as delegates, lambda expressions, and pattern matching. The book is divided into thoughtfully crafted sections that address both fundamental and advanced constructs crucial for leveraging functional programming in real-world scenarios. It explores LINQ for functional data processing, advanced error handling techniques, and asynchronous programming with task-based patterns, equipping readers with tools for efficient code execution and robust software design. Practical examples are woven throughout to illustrate the application of these concepts, ensuring readers gain hands-on experience in functional application development. As readers progress, they delve into practical applications of functional programming across various domains, from data analytics and web development to building robust microservices and event-driven architectures. This comprehensive guide not only demystifies functional programming but also empowers readers to apply these principles effectively in their projects, paving the way for innovative solutions and enhanced software performance. Whether integrating into existing frameworks or laying the groundwork for new projects, this book serves as an essential resource for mastering functional programming in C#.

There’s no need to fear going functional! This friendly, lively, and engaging guide is perfect for any perplexed programmer. It lays out the principles of functional programming in a simple and concise way that will help you grok what FP is really all about. In Grokking Functional Programming you will learn: Designing with functions and types instead of objects Programming with pure functions and immutable values Writing concurrent programs using the functional style Testing functional programs Multiple learning approaches to help you grok each new concept If you’ve ever found yourself rolling your eyes at functional programming, this is the book for you. Open up Grokking Functional Programming and you’ll find functional ideas mapped onto what you already know as an object-oriented programmer. The book focuses on practical aspects from page one. Hands-on examples apply functional principles to everyday programming tasks like concurrency, error handling, and improving readability. Plus, puzzles and exercises let you think and practice what you're learning. You’ll soon reach an amazing “aha” moment and start seeing code in a completely new way. About the technology Finally, there’s an easy way to learn functional programming! This unique book starts with the familiar ideas of OOP and introduces FP step-by-step using relevant examples, engaging exercises, and lots of illustrations. You’ll be amazed at how quickly you’ll start seeing software tasks from this valuable new perspective. About the book Grokking Functional Programming introduces functional programming to imperative developers. You’ll start with small, comfortable coding tasks that expose basic concepts like writing pure functions and working with immutable data. Along the way, you’ll learn how to write code that eliminates common bugs caused by complex distributed state. You’ll also explore the FP approach to IO, concurrency, and data streaming. By the time you finish, you’ll be writing clean functional code that’s easy to understand, test, and maintain.
