Programming Clojure Getting started Exploring Clojure Unifying data with sequences Functional programming Specifications State and concurrency Protocols and datatypes Macros Multimethods Java Interop Building an application Drowning in unnecessary complexity unmanaged state and tangles of spaghetti code In the best tradition of Lisp Clojure gets out of your way so you can focus on expressing simple solutions to hard problems. Clojure cuts through complexity by providing a set of composable tools immutable data functions macros and the interactive REPL. Written by members of the Clojure core team this book is the essential definitive guide to Clojure. This new edition includes information on all the newest features of Clojure such as transducers and specs. Clojure joins the flexibility and agility of Lisp with the reach stability and performance of Java. Combine Clojures tools for maximum effectiveness as you work with immutable data functional programming and safe concurrency to write programs that solve real world problems. Start by reading and understanding Clojure syntax and see how Clojure is evaluated. From there find out about the sequence abstraction which combines immutable collections with functional programming to create truly reusable data transformation code. Clojure is a functional language; learn how to write programs in a functional style and when and how to use recursion to your advantage. Discover Clojures unique approach to state and identity techniques for polymorphism and open systems using multimethods and protocols and how to leverage Clojures metaprogramming capabilities via macros. Finally put all the pieces together in a real program. New to this edition is coverage of Clojures spec library one of the most interesting new features of Clojure for describing both data and functions. You can use Clojure spec to validate data destructure data explain invalid data and generate large numbers of tests to verify the correctness of your code. With this book youll learn how to think in Clojure and how to take advantage of its combined strengths to build powerful programs quickly. provided by Amazon.com.
