Ruby is an open-source dynamic OO interpreted language created by Yukihiro Matsumoto (Matz) in the 1990s that combines the good bits from Perl, Smalltalk and Lisp. It supports multiple programming paradigms. Ruby's primary purpose is to "help every programmer in the world to be productive, and to enjoy programming, and to be happy." - Matz. Ruby mindshare spiked in the next decade due to Ruby on Rails - a popular web application framework built on Ruby.
