Functional Programming with C#

By: Alex Yagur

Overview of this book

In an era where software complexity is increasing by the day, functional programming offers a paradigm that simplifies code maintenance and enhances reliability. Functional Programming with C# takes you on an exhaustive journey into functional programming within C#. The book familiarizes you with the core principles and benefits of functional programming, juxtaposing it with imperative and object-oriented paradigms. You’ll get to grips with the functional features of C# and learn to write expressive, modular code through expressions, pure functions, and higher-order functions. As you advance, you’ll explore advanced concepts such as error handling and asynchronous programming, which will equip you with the practical skills that you need to tackle real-world challenges. By comparing functional programming in C# with other languages and providing additional resources, this book ensures that you’re well-equipped to continue your journey toward mastery in functional programming. By the end of this book, you’ll have gained a thorough understanding of functional programming techniques, such as recursion, memoization, and composition, empowering you to write robust, maintainable code.

Introducing recursion

As Steve continued developing his tower defense game, he found himself struggling with complex nested structures for enemy waves. He called Julia, hoping she might have some insights.

Julia: It sounds like you’re dealing with hierarchical data structures. Have you considered using recursion?

Steve: Recursion? Isn’t that when a function calls itself? It always seemed a bit confusing to me.

Julia: That’s right, but it’s a powerful tool for handling nested structures. Let’s explore how it could help with your game.

Recursion is a programming technique where a function calls itself to solve a problem. It’s like breaking down a task into smaller tasks of the same type. This approach is very useful for tasks that have a repetitive structure, such as navigating through folders and files, working with data structures such as trees, or doing calculations that follow a pattern.

In recursion, there are two main parts...
