A. Ignatov, I. V. Kuznetsov, A. A. Yuriev. This book is a guide to functional programming, which is a new approach to software development that emphasizes the use of pure functions, immutability, and the avoidance of changing state. The authors argue that this approach can lead to more reliable, maintainable, and efficient code, and they provide examples and exercises to help readers learn and apply these principles. The book begins by introducing the concept of functional programming and its benefits, including improved reliability, maintainability, and efficiency. The authors then delve into the details of functional programming, explaining how to write pure functions, use immutability, and avoid changing state. They also discuss common pitfalls and challenges of functional programming and how to overcome them. Throughout the book, the authors provide numerous examples and exercises to help readers understand and apply the concepts they are learning. These include simple programs that demonstrate the power of functional programming, as well as more complex examples that illustrate how to use functional programming in real-world applications. One of the key themes of the book is the importance of developing a personal paradigm for perceiving the technological process of developing modern knowledge. The authors argue that this is essential for survival in today's rapidly changing world, where technology is constantly evolving and new breakthroughs are being made. By understanding the underlying principles of technology, individuals can better navigate the complex landscape of modern knowledge and make informed decisions about their own development. The book also emphasizes the need for unity among people in a warring state, highlighting the importance of collaboration and cooperation in achieving common goals.
