Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.
Ruby was created as a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.
He has often said that he is "trying to make Ruby natural, not simple," in a way that mirrors life.
Building on this, he adds: "Ruby is simple in appearance, but is very complex inside, just like our human body."
