Ruby on Rails (Rails or RoR) is written in the Ruby programming language which is a dynamic, reflective, general purpose object-oriented programming language that merge syntax influenced by Perl with features like Smalltalk. It is designed to make web development faster, simpler and more efficient. It supports multiple programming paradigms like object oriented, functional and imperative. It is comparable in varying respects to Python, Perl, Dylan, Lisp and CLU because of its dynamic system and automatic memory management features. Ruby is a single-pass interpreted language in its current official implementation written in C and because there is no specification for the Ruby language, the implementation is measured to be a de facto reference.
