Oops stands for Object-Oriented Programming. The four pillars of Oops are Inheritance, Encapsulation, Abstraction, and Polymorphism.
Inheritance allows a class to inherit properties and behavior from another class. For example, a 'Car' class can inherit from a 'Vehicle' class.
Encapsulation refers to the bundling of data and methods that operate on the data into a single unit. For example, using private variables and pub...

Mixins in Ruby are a way to add functionality to a class without inheritance.
Mixins are modules that can be included in a class to extend its functionality.
They allow for code reuse and help avoid duplication.
Mixins are included using the 'include' keyword in Ruby.
extend adds class methods, prepend adds instance methods, include adds module methods
extend adds methods to a class as class methods
prepend adds methods to a class as instance methods
include adds methods to a class as module methods
Class methods are called on the class itself, while instance methods are called on instances of the class.
Class methods are defined using 'self' keyword in the method name.
Instance methods are defined without 'self' keyword in the method name.
Class methods are used for operations that are not specific to any instance of the class.
Instance methods are used for operations that are specific to individual instances of the
