Clojure is a general-purpose, functional programming language hosted on the Java Virtual Machine. It is a homoiconic S-expression language that represents programs as nested data structures, allowing code to be manipulated and evaluated as data.
The project provides a framework for JVM interoperability, enabling the invocation of Java methods and integration with other JVM-based languages. It distinguishes itself through a persistent data structure library that uses bitmapped vector tries to manage immutable collections and a programmatic REPL for interactive software development and real-time library loading.
The system includes capabilities for parallel data processing using a fork-join model and data transformation via transducers. It also covers protocol-based polymorphism, metadata-driven dispatch, and a compilation process that transforms high-level expressions into Java bytecode.
The runtime supports remote access to interactive environments via socket server initialization.
