Q&A

What's different between module and class?

Ruby Modules are similar to classes in that they hold a collection of methods, constants, and other module and class definitions. Modules are defined much like classes are, but the module keyword is used in place of the class keyword. Unlike classes, you cannot create objects based on modules nor can you subclass them; instead, you specify that you want the functionality of a particular module to be added to the functionality of a class, or of a specific object. Modules stand alone; there is no "module hierarchy" of inheritance. Modules is a good place to collect all your constants in a central location.
