Chapter 1. Ruby Pocket Reference
Ruby is an open source, object-oriented programming language created by Yukihiro “Matz” Matsumoto. First released in Japan in 1995, Ruby has gained worldwide acceptance as an easy-to-learn, powerful, and expressive language, especially since the advent of Ruby on Rails, a web application framework written in Ruby (http://www.rubyonrails.org). Ruby’s core is written in the C programming language and runs on all major platforms. It is an interpreted rather than compiled language. For more information on Ruby, see http://www.ruby-lang.org.
