/**
 * Example JavaScript code to demonstrate how to compose classes.
 * This requires ES6 syntax.
 *
 * `Transportation` is a base class that is intended to have classes derived from it.
 * Derived classes are expected to manage the base class properties and add their own.
 * In each constructor, `super` is called first to allow the base class to perform its state
 * initialization before the derived class do its, allowing the derived class to override
 * anything done in the base class constructor.
