Classes are blueprints. Objects are known as 'instances' of these classes.
Classes are where we define all variables and methods.

Instance variables (@var_name) and instance methods (def method_name) belong only to objects and are accessed using dot notation (Object.name) on an object made using 'Class.new'.




Class variables (var_name)

, constants (VAR_NAME), and class methods (def self.method_name) belong only to the class and are accessed using 'Class::name'
