Ruby on Rails

Ruby is a general-purpose dynamic programming language. Having been inspired by Smalltalk, Ruby displays a very high degree of object orientation, but it also features Perl's strong text processing and Unix programming abilities and Lisp's metaprogramming facilities.

The language was created in 1995 by Yukihiro Matsumoto, often referred to as "Matz" in the Ruby community, and is now at version 2.1. Ruby has a strong focus on programmer happiness, its motto being "A programmer's best friend". It achieves that goal by being simple, powerful, practical and predictable. It features elegant and readable syntax that is easy to write and read, as well as nice APIs to use and a great standard library. When learning, you can often guess a method name correctly.
