Ruby is a dynamic object-oriented programming language designed and developed during the mid-1990s by Yukihiro “Matz” Matsumoto in Japan. According to Mr. Matsumoto, Perl, Smalltalk, Eiffel, Ada, and Lisp influenced Ruby’s initial structure. Ruby supports multiple programming paradigms, including functional, object-oriented, and imperative. It also has a dynamic type system and offers automatic memory management.
The name “Ruby” comes from an online chat session between Matsumoto and his colleague Keiju Ishitsuka. Initially two names were proposed: “Coral” and “Ruby”. Matsumoto chose the latter because it was the birthstone of one of his colleagues.
