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.
While I managed to produce programs that solved real-world problems they never felt quite right. Common Lisp was still a more natural technology to me. Perhaps that's one of the reasons; Clojure parts with traditional Lisps in both philosophy and surface.
It has a different solution space and it took me some time to really get into the mindset. I recently decided to perform an on-line experiment for my master thesis in psychology. Although slipping somewhat in scope, there was no way I could resist the technical temptation; I just had to develop my app in Clojure using MongoDB as back-end through the excellent Clojure Monger client.
Clojure turned out great MongoDB was a pleasure too. It was quite fascinating and rewarding to note how my solutions grew shorter and simpler as my skill set grew.
After many hard hours, the power of Clojure started to shine as each refactoring now left me with less yet more expressive code. That's what I like about Lisp; there are no artificial constraints enforced upon the programmer.
Sure, the restrictions on what you can express are still there. But those restrictions are right where they should be: on the skills and creativity of the programmer. Clojure Programming came just right for my project.
I still got a lot to learn but the book smoothed my initial learning curve and finally taught me efficient and idiomatic Clojure. 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.
Finally, put all the pieces together in a real program. 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.
Rely on your REPL. We are fortunate to have a variety of tool choices in Clojure that can satisfy those demands. Maps, not Objects. Developers coming from object-oriented languages are likely to look for the ability to create classes or objects to hold their data.
Clojure takes a more direct and flexible approach to data, primarily storing information attributes in heterogenous maps. Rather than providing class-specific interfaces, Clojure provides a single generic data interface for creating, accessing, and transforming attribute-oriented information. The result is that modeling data and managing the evolution of data over time is generally much more generic and immediate than the equivalent operations in object-oriented languages.
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. But it quickly moves into macros and the more technical concepts behind Clojure programming. The author even touches upon ClojureScript which is a pleasant yet unrelated surprise.
Everything in this book is dense and comprehensive. What you get is a lot more detail on the main topics like concurrency and parallelism in Clojure app development.
The text is very heavy and full of tech jargon so it will scare off beginners.
But as the language gains momentum this is something worth discussing and studying if you have the time. Web Development with Clojure by Dmitri Sotnikov is a page book first released in the summer of The author Dmitri talks about Clojure in a web workflow including many popular libraries, frameworks, and 3rd party tools like Compojure. I do not think a typical web developer could just pick up this book and go to town.
You do need some functional programming experience because Clojure on the web is very complicated.
The majority of JS libraries offer this functionality and I was surprised to see it as part of Clojure too. But the author walks you through many common techniques for building reactive frameworks and components on Clojure.
These include real examples like a game built on ClojureScript and components built on the RxJS library. Get comfortable with Clojure before picking up this book. Clojure Applied: From Practice to Practitioner Too many programming books focus on theory and not enough force you into action.
This is the beauty of Clojure Applied because it works in your favor to force you to take real actionable steps. I do think this book works better for someone who already understands the basics of functional programming even in a different language. But it is possible for a complete beginner to grab a copy and learn Clojure through these practical tutorial examples.
Many of the tutorials go into great detail but the authors take their time explaining common pitfalls and confusing areas. This book covers the essentials and gets you up to speed with real world Clojure development. This book delves into a wide range of topics for Clojure development including workflows and best tools for enhancing your projects. Everything this book talks about is practical and detailed.
