Programming Clojure

Find out why Clojure is Java.next:

  • Clojure provides clean, fast access to all Java libraries.
  • Clojure provides all the low-ceremony goodness you know and love from dynamic languages such as Ruby and Python.
  • Clojure includes Lisp's signature feature: Treating code as data through macros.
  • Clojure's emphasis on immutability and support for software transactional memory make it a viable option for taking advantage of massively parallel hardware.

Clojure is a dynamic programming language for the Java Virtual Machine, with a compelling combination of features:

  • Clojure is elegant. Clojure?s clean, careful design lets you write programs that get right to the essence of a problem, without a lot of clutter and ceremony.
  • Clojure is Lisp reloaded. Clojure has the power inherent in Lisp,
    but is not constrained by the history of Lisp.
  • Clojure is a functional language. Data structures are immutable, and most functions are side-effect free. This makes it easier to write correct programs, and to compose large programs from smaller ones.
  • Clojure simpli?es concurrent programming. Of course, Java itself has pretty good concurrency support. But, there is wide agreement that lock-based concurrency is dif?cult to use correctly. Clojure provides alternatives to lock-based concurrency: software transactional memory, agents, and dynamic variables.
  • Clojure embraces Java. Calling from Clojure to Java is direct, and goes through no translation layer.
  • Unlike many popular dynamic languages, Clojure is fast. Wherever you need it, you can get the exact same performance that you could get from hand-written Java code.
