'''Ruby''' is a [[general-purpose programming language]]. It was designed with an emphasis on programming productivity and simplicity. In Ruby, everything is an [[object (computer science)|object]], including [[primitive data type]]s. It was developed in the mid-1990s by [[Yukihiro Matsumoto|Yukihiro "Matz" Matsumoto]] in [[Japan]].

Ruby is [[interpreted language|interpreted]], [[high-level programming language|high-level]], and [[Dynamic typing|dynamically typed]]; its interpreter uses [[garbage collection (computer science)|garbage collection]] and [[just-in-time compilation]]. It supports multiple programming paradigms, including [[procedural programming|procedural]], [[object-oriented programming|object-oriented]], and [[functional programming]]. According to the creator, Ruby was influenced by [[Perl]], [[Smalltalk]], [[Eiffel (programming language)|Eiffel]], [[Ada (programming language)|Ada]], [[BASIC]], and [[Lisp (programming language)|Lisp]].<ref name="about"/><ref name="confreaks" />
