What are modules in Ruby? How do they enhance code reusability and organization?

In Ruby, modules are containers for organizing and grouping related methods, constants, and other module definitions. They provide a way to achieve code reusability and maintainability by encapsulating functionality into separate units. Modules act as mixins, allowing classes to incorporate their behavior using the `include` keyword. This concept is known as mixin inheritance, and it enables multiple classes to share common methods and constants defined within a module. One of the primary benefits of using modules is code reusability. By defining common functionality in a module, you can include that module in multiple classes, allowing them to access and utilize the methods defined within it. This promotes the DRY (Don't Repeat Yourself) principle and reduces code duplication. Instead of writing the same code in multiple classes, you can define it once in a module and include that module wherever it's needed. Modules....
