Description: The module function in Ruby is a method defined within a module that can be invoked as a function. Modules in Ruby are collections of methods, constants, and classes that can be used to organize and encapsulate code. By defining a function within a module, it allows that function to be accessible from anywhere in the program, as long as the module is included or extended. This promotes code reuse and modularity, making it easier to manage larger and more complex projects. Module functions are particularly useful for grouping related functionalities and avoiding pollution of the global namespace. Additionally, by using modules, developers can avoid name conflicts and improve code readability. In Ruby, modules can also be used as mixins, allowing classes to inherit methods from a module without the need for a complex class hierarchy. This provides great flexibility and power in object-oriented programming, enabling developers to build more robust and maintainable applications.
