➢ Ruby Programming Language: RoR is written in the Ruby programming language. So it enables users to take advantage of a modern and powerful programming language like Ruby. Ruby is inspired by several programming languages including Perl, Ada, Lisp, Eiffel and SmallTalk. In addition to supporting object-oriented, functional and imperative programming paradigms, Ruby also comes with automatic memory management and dynamic type system. So it becomes easier for programmers to accomplish complex tasks without writing longer lines of code.

➢ Full Stack Framework: Unlike other web application development frameworks, RoR is full stack. It comes with features to cover development of both frontend and backend. So the developers are not required to use any third-party tools or frameworks to build the entire web application. When a programmer starts learning RoR, he will have working knowledge of widely used web technologies like HTML, CSS and JavaScript. So the same developers can take advantage of the features provided by RoR to create the frontend and backend of the web application without any hassle.

➢ Ruby Gems: Ruby Gems further make RoR score over other web application development frameworks. The users can take advantage of the Ruby package manager to simplify the development and distribution of various libraries or gems. They can further make the libraries or gems available to other web developers by uploading the resources to the RubyGems website. At the same time, the developers also have option to save time by using the RubyGems shared by other programmers. However, they need to understand in exact installation process of the particular gem, as the installation process differs from one library to another.

➢ Supports MVC Development Pattern: RoR simplifies development of large and complex web applications by supporting the model-view-controller (MVC) development pattern. It provided default structure for development of web pages, web services and databases. It allows developers to create the user interface and display using HTML, JavaScript and CSS. Likewise, it emphasizes on use of web standard like XML and JSON for data transfer. The MVC pattern further enables developers to build large applications into small modules, and work of various modules simultaneously. They can further simplify and speed up development by working on the business logic and presentation separately and simultaneously.

➢ Focus on Testing: In addition to including a good testing framework, RoR also has strong focus on testing. When the programmers work on models and controllers, the framework will produce skeleton test code. So the developers can run the tests repetitively to ensure that the code meets the predefined functionality. They can even run the tests after making changes to the code to ensure that the application runs flawlessly. As the RoR tests can simulate browser tests, the websites can also be tested without using multiple web browsers. The enhanced focus on testing also makes RoR score over other popular web application development frameworks.
