// == Ideas/Terms ==

// * OOD/OOP: Object-Oriented Design/Programming
//            * Encapsulate behavior of each "noun"
//              > protects state changes (more next week!)
//              > features/changes localized
//            * Abstraction via masking implementation
//              (🔑 + 🚗 -> 🏖️)

// * Class:   A data type (e.g., String, IntRange, FullName)
//            Every data type in Kotlin is a class, 
//            though some other OO languages (e.g., Java) 
//            distinguish "primitive" types

// * Object:  An instance of a type, e.g... 
//            "howdy", 1..5, FullName("harry", "potter")

// * Member:  Data or function within a class
//            via object.memberData / object.memberFunc()
//            * Each object gets its own data, 
//              but "shares" the functions
//            * Synonyms... 
//              > member data: field, property, attribute
//              > member functions: methods
