DEV Community

All articles and discussions should be about the Ruby programming language and related frameworks and technologies like Rails, Hanami, Sinatra etc. Please also add the relevant library tags when making a post.

Questions are encouraged! Including the #help tag will make them easier to find.

Ruby is an open-source dynamic object-oriented interpreted language that combines the good bits from Perl, Smalltalk, and Lisp. It supports multiple programming paradigms including functional, object-oriented, and imperative.

Ruby was initially conceived on February 24, 1993, by Yukihiro Matsumoto ('Matz') and version 1.0 was released in 1996
