Ruby programming language

Books on this shelf deal with the Ruby programming language: a dynamic, reflective, general purpose object-oriented programming language that combines syntax inspired by Perl with Smalltalk-like features. It is based on Perl, Smalltalk, Eiffel, Ada, and Lisp. Ruby supports multiple programming paradigms, including functional, object oriented, imperative, and reflective. It also has a dynamic type system and automatic memory management.
