As there is currently no specification of the Ruby language, this implementation is considered the de facto reference. In 2008, there are a number of alternative implementations of the Ruby language, including Rubinius, JRuby, YARV and IronRuby, each with a different approach, with JRuby providing just-in-compile-time language has functionality.The was created by Yukihiro Matsumoto, who started working on Ruby, February 24, 1993, and communicated to the public in 1995.
