 Introduction to Ruby

Ruby is a pure object-oriented programming language. It was founded in 1993 by Yukihiro Matsumoto (Yukihiro Matsumoto).

You can find the name of Matsumoto Hiroshi (Yuhiro Matsumoto) on the Ruby mailing list at www.ruby-lang.org. In the Ruby community, Matsumoto is also called Matz.

Ruby is "the best friend of programmers".

Ruby's features are similar to Smalltalk, Perl, and Python. Perl, Python, and Smalltalk are scripting languages. Smalltalk is a true object-oriented language. Ruby, like Smalltalk, is a perfect object-oriented language. Using Ruby's syntax is much easier than using Smalltalk's syntax.
