Inheritance in JavaScript

 Inheritance in JavaScript

Inheritance is a feature of OOP that allows you to create new classes based on existing classes. In JavaScript, you can use the extends keyword to create a subclass that inherits from a superclass.

Here's an example of how to create a subclass in JavaScript:

class Student extends Person {

  constructor(name, age, grade) {

    super(name, age);

    this.grade = grade;

  }

  

  sayHello() {

    console.log(`Hello, my name is ${this.name} and I'm a student in grade ${this.grade}.`);

  }

}

const student = new Student('Jane', 17, 11);

student.sayHello(); // prints "Hello, my name is Jane and I'm a student in grade 11."
