Class Inheritance Hierarchy in OOP in JavaScript

It is possible to inherit from a class that is itself a descendant. Let's look at an example. Let's say we have the following parent class:

class User {
	setName(name) {
		this._name = name;
	}
	getName() {
		return this._name;
	}
}

The following class inherits from this class:

class Student extends User {
	setYear(year) {
		this._year = year;
	}
	getYear() {
		return this._year;
	}
}

And another class inherits from this class:

class StudentProgrammer extends Student {
	setSkill(skill) {
		this._skill = skill;
	}
	getSkill() {
		return this._skill;
	}
}

Make a class Employee that will inherit from the class User.

Make a class Programmer that will inherit from the class Employee.

Make classes Designer that will inherit from class Employee.

Add various methods to the classes you created.
