Clojure for Java Developers

Clojure for Java Developers

Presented by John Stevenson (http://blog.jr0cket.co.uk/) (@jr0cket (https://twitter.com/jr0cket))

Learning a new language is one of the best things a developer can do to broaden their experience and adapt different approaches into their work. The greater the difference in language principles and syntax, the more you can benefit. Learning a functional programming language can also help you make more of the current trend of multi-core CPU architecture.

Clojure (http://clojure.org/) is a new functional programming language for the Java platform and yet based on one of the oldest languages still in use, Lisp (http://en.wikipedia.org/wiki/Lisp_%28programming_language%29). Clojure in my humble opinion is one of the most beautiful languages I have used. Its simplicity of syntax & design approach makes it a really powerful general purpose language.

Using the concept of REPL driven programming, I will introduce you to the concept and syntax of the language. I'll also cover the key tools and libraries that help you develop applications quickly and effectively. Topics include:

• Clojure syntax & the dynamic nature of Clojure
• Atomic & aggregate data types
• Java interoperability & underlying Java objects
• Immutability & managing state
• Homoiconisity & macros
• Building Clojure projects & dependency management with Leiningen (http://leiningen.org/)
• Repl driven programming with LightTable (http://www.lighttable.com/) & Emacs

Maybe some graphics fun with Quil (https://github.com/quil/quil) if there is time!

Who should attend:

This session is suitable for anyone who is a developer, or studying to be a developer. Whilst comparisons will be made to the Java language, tools & ecosystem, Java is not a pre-requisite to discover Clojure.
