Ruby is a general-purpose programming language designed with an emphasis on programming productivity and simplicity. In Ruby, everything is an object, including primitive data types. Development of the language began in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan.
Ruby is interpreted, high-level, and dynamically typed; its interpreter uses garbage collection and just-in-time compilation. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. According to the creator, Ruby was influenced by Perl, Smalltalk, Eiffel, Ada, BASIC, and Lisp.
