Clojure is a dialect of the Lisp programming language. It’s a well-rounded language. It offers broad library support and runs on multiple operating systems.
Clojure is a dynamic functional general purpose programming language that runs on the Java platform, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multi-threaded programming. Clojure features a rich set of immutable, persistent data structures, first-class functions and dynamic typing. Clojure programs are composed of expressions and written in terms of abstractions.
By compiling into JVM bytecode, Clojure applications can be easily packaged and deployed to JVMs and application servers without added complexity. The language also provides macros which make it simple to use existing Java APIs. Clojure’s data structures all implement standard Java Interfaces, making it easy to run code implemented in Clojure from Java.
There’s lots of other good reasons to learn Clojure. It offers a modern take on Lisp. There’s an excellent parser library, and a fully featured logic engine. In Clojure, immutability is the default. Once an object or data structure is created, it cannot be changed. There are no variables.
Clojure currently ranks 61th in the TIOBE Index.
Here’s our recommended tutorials to learn Clojure. If you’re looking for free Clojure programming books, check here.
