JRuby
A complete, high-performance implementation of the Ruby programming language that runs on the Java Virtual Machine (JVM).
What is JRuby?
JRuby is an implementation of the Ruby programming language that runs on the Java Virtual Machine (JVM). It provides a compatible Ruby runtime while enabling integration with Java libraries and tools. This allows developers to write Ruby code that can leverage Java's performance, concurrency features, and extensive ecosystem.
Ruby developers who need to integrate with Java ecosystems, Java developers who want to use Ruby for scripting or specific components, and teams working in polyglot environments that combine Ruby and Java technologies.
JRuby offers the best of both worlds: Ruby's expressive syntax and developer productivity combined with Java's performance, scalability, and vast library ecosystem. Its lack of a Global Interpreter Lock enables true parallelism, making it particularly valuable for concurrent applications.
