Overview of this book

Functional programming enables you to divide your software into smaller, reusable components that are easy to write, debug, and maintain. Combined with the power of C++, you can develop scalable and functional applications for modern software requirements. This book will help you discover the functional features in C++ 17 and C++ 20 to build enterprise-level applications. Starting with the fundamental building blocks of functional programming and how to use them in C++, you’ll explore functions, currying, and lambdas. As you advance, you’ll learn how to improve cohesion and delve into test-driven development, which will enable you in designing better software. In addition to this, the book covers architectural patterns such as event sourcing to help you get to grips with the importance of immutability for data storage. You’ll even understand how to “think in functions” and implement design patterns in a functional way. By the end of this book, you’ll be able to write faster and cleaner production code in C++ with the help of functional programming.

An introduction to functional programming

My first experience with functional programming was at university. I was a 20-year-old geek who was interested in Sci-Fi, reading, and programming; programming was the highlight of my academic life. Everything to do with C++, Java, MATLAB, and a few other programming languages that we used was fun for me. Unfortunately, I can't say the same thing about the disciplines around electrical engineering, circuits, or compiler theory. I just wanted to write code!

Based on my interests, functional programming should have been a very fun course for me. Our teacher was very passionate. We had to write code. But something went wrong—I didn't click with what the teacher was telling us. Why were lists so interesting? Why was the syntax so backward and full of parentheses? Why would I use these things when it was much simpler to write...
