"Functional and Logical Programming" by A. T. Kovalkova and . A. Kovalkova is a fascinating and deep immersion into the world of two powerful programming paradigms that are becoming increasingly relevant in the modern IT space. With the rapid development of technology and the constant search for optimal solutions for complex problems, understanding functional and logical programming becomes necessary for every programmer seeking professional growth and expansion of his skills. The authors, possessing rich experience in computer science and programming, offer the reader not only theoretical calculations, but also practical examples that help to better understand and master the material. The book covers a wide range of topics, ranging from the basics of functional programming to more complex concepts such as lazy computing and data processing. Logical programming, in turn, is viewed through the lens of languages such as Prolog, allowing the reader to see how these ideas are applied in practice. This book will be of interest to both novice programmers and experienced developers who want to deepen their knowledge in the field of functional and logical approaches. Students studying computer science, as well as professionals working in the field of software development, will find a lot of useful information in it. Readers interested in new approaches to solving problems will be able to discover new horizons and methods that will help them in their professional activities. The topics raised in the book cover not only the technical aspects of programming, but also philosophical issues related to the choice of paradigm. The authors discuss how functional programming contributes to the creation of cleaner and more predictable code, and logical programming opens up new opportunities for solving problems related to artificial intelligence and knowledge processing. These ideas make the book especially valuable for those who seek not only to write code, but also to understand the foundations on which modern programming is based. The style of Kovalkov and Kovalkova is distinguished by clarity and accessibility . They are able to explain complex concepts in simple and understandable language, which makes the book an ideal tool for self-education. The authors also use many practical examples and tasks, which allows the reader not only to assimilate the theory, but also to apply it in practice. This makes "Functional and logical programming" not just a textbook, but a real guide to the world of modern technology. If you are looking for programming books that will help you master functional and logical approaches, then this publication will be a real find for you. It can be useful in combination with other works such as Haskell Programming or Artificial Intelligence: A Modern Approach by Stuart Russell and Peter Norvig. Readers interested in learning new programming languages, such as Scala or Elixir, will also find this book a lot of useful. Thus, “Functional and Logical Programming” is not just a book, but a whole world of possibilities that opens up to everyone who is ready to immerse themselves in the study of these exciting and powerful paradigms. Do not miss the chance to expand your horizons and become part of a new generation of programmers who understand how and why modern technologies work.
