Learn all about Ruby on Rails

Ruby on Rails, often simply referred to as Rails, is a popular open-source web application framework written in Ruby. It follows the Model-View-Controller (MVC) architectural pattern and provides developers with a productive and elegant way to build dynamic, database-backed web applications. Rails emphasizes convention over configuration, allowing developers to focus on writing application logic rather than dealing with repetitive setup tasks.
