Kiumzishi instanceof katika OOP katika JavaScript

Kiumzishi instanceof huruhusu kuangalia kama kitu ni cha darasa fulani. Tuangalie kwa mfano. Hebu tuwe na darasa lifuatalo:

javascriptclass User {
  
}

Tutengeneze kitu kutoka kwa darasa hili:

javascriptlet user = new User;

Tuangalie, kama kitu kutoka kwenye kibadilishaji ni cha darasa letu:

javascriptconsole.log(user instanceof User); // true

Amua, matokeo yatakuwaje ya kutekeleza msimbo ufuatao:

javascriptclass Student {
  
}
class Employee {
  
}

let employee = new Employee;
console.log(employee instanceof Employee);
console.log(employee instanceof Student);

Задание 2

Kuna msimbo ufuatao:

javascriptclass Student {
  constructor(name) {
    this.name = name;
  }
}
class Employee {
  constructor(name) {
    this.name = name;
  }
}

let users = [
  new Student('user1'),
  new Employee('user2'),
  new Student('user3'),
  new Employee('user4'),
  new Student('user5'),
  new Employee('user6'),
  new Student('user7'),
];
