Descendant Methods in OOP in JavaScript

A descendant class can have its own methods. For example, let's add a getter and setter for our student's year of study:

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

The child class will have both its private methods and inherited ones available. Let's check. Let's create an object of the class:

javascriptlet student = new Student;

Let's set its name using the inherited method, and its year of study using our own method:

javascriptstudent.setName('john');
student.setYear(1);

Let's read his name and year of study:

javascriptlet name = student.getName();
let year = student.getYear();

console.log(name, year);
