Clojure – Functional Programming for the JVM is an informative and practical guide that introduces readers to the programming language Clojure and its functional programming concepts. The book is written by seasoned software developer and Clojure expert, Dean Wampler, and published by O’Reilly Media.

The book begins by providing a brief overview of functional programming, explaining its benefits and why it has become increasingly popular in recent years. It then delves into the specifics of Clojure, a dynamic, modern, Lisp-like programming language that runs on the Java Virtual Machine (JVM). Readers will learn how to install and set up the necessary tools to start programming in Clojure.

The author takes a step-by-step approach to teach readers the fundamentals of Clojure, starting with basic syntax, data types, and collections. From there, the book moves on to cover more advanced topics, including higher-order functions, concurrency, and parallelism. Throughout the book, the author emphasizes the benefits of using a functional programming approach, such as immutability, statelessness, and composability.

One of the strengths of Clojure is its ability to interoperate with Java libraries, which is also covered in the book. Readers will learn how to use Java libraries and frameworks from within their Clojure code, as well as how to create Java classes and interfaces from Clojure.

The book also includes several practical examples and exercises that help readers apply what they’ve learned. These examples range from simple tasks like calculating the sum of a list of numbers to more complex tasks like creating a web application.

Overall, Clojure – Functional Programming for the JVM is an excellent resource for software developers who are interested in learning functional programming and Clojure. The book’s clear and concise writing style, coupled with practical examples and exercises, make it a valuable addition to any developer’s bookshelf.
