const ceo: Employee = {
    uniqueId: 1,
    name: 'Mark Zuckerberg',
    subordinates: [],
}
const orgApp = new EmployeeOrgApp(ceo);
const Sarah_Donald = orgApp.add("Sarah Donald", ceo.uniqueId);
const Cassandra_Reynolds = orgApp.add("Cassandra Reynolds", Sarah_Donald.uniqueId);
const Mary_Blue = orgApp.add("Mary Blue", Cassandra_Reynolds.uniqueId);
const Bob_Saget = orgApp.add("Bob Saget", Cassandra_Reynolds.uniqueId);
const Tina_Teff = orgApp.add("Tina Teff", Bob_Saget.uniqueId);
const Will_Turner = orgApp.add("Will Turner", Bob_Saget.uniqueId);
const Tyler_Simpson = orgApp.add("Tyler Simpson", ceo.uniqueId);
const Harry_Tobs = orgApp.add("Harry Tobs", Tyler_Simpson.uniqueId);
const Thomas_Brown = orgApp.add("Thomas Brown", Harry_Tobs.uniqueId);
const George_Carrey = orgApp.add("George Carrey", Tyler_Simpson.uniqueId);
const Gary_Styles = orgApp.add("Gary Styles", Tyler_Simpson.uniqueId);
const Bruce_Willis = orgApp.add("Bruce Willis", ceo.uniqueId);
const Georgina_Flangy = orgApp.add("Georgina Flangy", ceo.uniqueId);
const Sophie_Turner = orgApp.add("Sophie Turner", Georgina_Flangy.uniqueId);
console.log(JSON.stringify(ceo));
