Ruby on Rails fondly called as Rails or RoR was developed by Ruby. RoR is an open source framework focused on web development. Similar to Perl and Python, Ruby is also an object-oriented programming language. Developers prefer RoR to other frameworks because the Ruby-based framework is 5 to 10 times faster when compared to Java-based frameworks. With RoR, changes made can be applied immediately and eradicate the time-consuming steps usually associated with the web development process.
