A Ruby module is a crucial component of Ruby's programming language. It supports multiple inheritance and is a key object-oriented element of the language.
Object-oriented programming (OOP) is a programming model that includes ideas such as inheritance, abstraction, polymorphism, and others. These ideas are aimed at incorporating real-world entities into computer applications. They develop working techniques and variables that they may reuse without jeopardizing security.
To summarize, Ruby treats practically everything as an object. Every data type we work with is an object, and objects are classes. The Object class is an object as well. Objects include strings, integers, floats, hashes, arrays, symbols, classes, modules, errors, and more.
