When Ruby on Rails, a web application framework written in the Ruby programming language, was first released as open source back in July 2004, it stumbled to rise in the rankings as one of the top programming languages. But in 2006, Apple announced that it would be shipping Ruby on Rails with their Mac OS X v10.5 “Leopard” and Ruby soon became known and used by many. So much so, that the TIOBE index, a measure of the popularity of programming languages, named Ruby the “Programming Language of 2006.” However, due to some scalability issues and the release of other exciting new tools, such as Node.js and AngularJS, Ruby started to lose its popularity and by 2008 it seemed as if it was on its way out.
