Mastering Clojure

Overview of this book

Clojure is a general-purpose language from the Lisp family with an emphasis on functional programming. It has some interesting concepts and features such as immutability, gradual typing, thread-safe concurrency primitives, and macro-based metaprogramming, which makes it a great choice to create modern, performant, and scalable applications. Mastering Clojure gives you an insight into the nitty-gritty details and more advanced features of the Clojure programming language to create more scalable, maintainable, and elegant applications. You’ll start off by learning the details of sequences, concurrency primitives, and macros. Packed with a lot of examples, you’ll get a walkthrough on orchestrating concurrency and parallelism, which will help you understand Clojure reducers, and we’ll walk through composing transducers so you know about functional composition and process transformation inside out. We also explain how reducers and transducers can be used to handle data in a more performant manner. Later on, we describe how Clojure also supports other programming paradigms such as pure functional programming and logic programming. Furthermore, you’ll level up your skills by taking advantage of Clojure's powerful macro system. Parallel, asynchronous, and reactive programming techniques are also described in detail. Lastly, we’ll show you how to test and troubleshoot your code to speed up your development cycles and allow you to deploy the code faster.

Chapter 7. Programming with Logic

We will now take a step back from the realm of functional programming and explore a completely different paradigm—logic programming. Logic programming has its own unique way of solving computational problems. Of course, logic programming isn't the only way to solve a problem, but it's interesting to see what kind of problems can be easily solved with it.

Although logic programming and functional programming are two completely different paradigms, they do have a few commonalities. Firstly, both of these paradigms are forms of declarative programming. Studies and papers have also shown that it is possible to implement the semantics of logic programming within a functional programming language. Hence, logic programming operates at a much higher degree of abstraction than functional programming. Logic programming is more suited for problems in which we have a set of rules, and we intend to find all the possible values that conform to these rules.
