{"mvc": "Model-View-Controller (MVC) is a design pattern used in software engineering to separate an application into three interconnected components: Model, View, and Controller. Each component has its own responsibilities.","why_use_it": "The main benefit of using MVC is separation of concerns, which makes the code easier to maintain, test, and scale. The model deals with data logic, the view handles user interface, and the controller manages input and output between the two."

Tell me the role of modules and mixins in ruby?
