I found Clojure Programming by Chas Emerick et al to be a good learning . My favorite Clojure book is Web Dev with Clojure 2nd edition. Clojure is a practical, general-purpose language that offers expressivity rivaling other dynamic languages like Ruby and Python, while seamlessly taking. This book helps you learn the fundamentals of Clojure with examples relating it to the languages you know already, in the domains and topics you work with.
Collections, not Loops. Imperative languages encourage you to write loops that manipulate data elements one-by-one. In Clojure, you instead think primarily in collections, not loops.
When transformations need to be applied, you use a functional approach to describe the transformation from one collection to another, which may involve mapping, filtering, or otherwise transforming data at the collection level. Isolate State. However, most Clojure developers minimize the number of functions that work with these kinds of constructs. As much as possible, Clojure functions tend to be small and pure, just simple transformations of data to data.
Stateful change thus becomes little more than the application of pure functions to data. Have Fun! There is very little ceremony in the code, a literal syntax to easily represent data, a huge library of functions available for transforming data, and access to all of the existing functionality of the underlying host platform via either interop or libraries.
Clojure gets out of the way and lets you get to work! A: The first edition of Programming Clojure was important because it was the first Clojure book available.
Stuart Halloway worked closely with Rich Hickey, the creator of Clojure, to capture the key ideas behind Clojure and let that philosophy shine through. I first picked up Clojure about the time this book was published and I found it to be a helpful and insightful guide.
It has been a great challenge and pleasure to revisit this material that I used to learn Clojure myself from the other side of the page. A: Aaron Bedra provided an excellent update in the second edition of Programming Clojure for the release of Clojure 1. In this third edition, everything has been brought up to date with Clojure 1. I have included new material on features added since the last edition like transducers and spec.
Additionally, many of the longer examples have been updated to take advantage of the latest features and functions of the language. Q: What kinds of problems are best solved with Clojure?
I've followed no one's advice though--I have not started small, and instead keep jumping into sophisticated middle parts and getting mired. At pages , Clojure Programming is hardly a tome, but it is comprehensive, appreciably thorough, and makes a concerted effort to be accessible to the Clojure and JVM neophyte.
But this head-first approach is one of the reasons to love this book.
Emerick et al. As such, the book is broken into five sections: 1. Functional Programming and Concurrency the foundation ; 2.
Building Abstractions the sophisticated stuff ; 3. Tools, Platform, and Projects the eco-system ; 4.
Practicums Clojure in the real world ; and 5. Miscellanea other important stuff.
What's marvelous about this structure is that you can decide for yourself whether to read it cover-to-cover, or whether to cherry-pick just the chapters relevant to your immediate challenges. What's helpful is that the book cross-references itself for many key concepts. In the thick of chapter one and you don't know what this "classpath" nonsense is?
Jump ahead to chapter eight! A footnote steers you back to chapter six! The care taken to create these kinds of cross-references is tremendously valuable because it allows you to opt-in to some advanced concepts early on, getting a preview of the powerful features ahead of you.
Though Clojure Programming is overflowing with thoughtful, detailed, and well-composed information, where it really shines is the "Practicums" section.
