JRuby is a high-performance and stable implementation of the Ruby programming language, running on the Java Virtual Machine (JVM). With JRuby, you get the best of both worlds - the simplicity and expressiveness of Ruby, along with the power and portability of Java. JRuby offers real threading and exceptional performance, making it suitable for high-performance applications.

It also provides a vast array of libraries, allowing you to easily leverage existing Java libraries within your Ruby code. Installing and migrating to JRuby is hassle-free, thanks to its platform independence and easy installation process. Simply extract it into a directory and add the directory's bin subdirectory to your path.

Testing it is as simple as running jruby -v in your command line. Stay up-to-date with the latest news and developments by visiting the JRuby website, where you can find helpful documentation, community chat, JavaDocs and RDocs, and more. You can also join the mailing lists, check out the issue tracker, and chat with the JRuby team.

JRuby has received accolades over the years, including the InfoWorld 2010 Bossie Award for Best Open Source Software. Explore the possibilities with JRuby and unlock the potential of combining Ruby and Java in your projects
