Inheritance in Classes

We also learned how to inherit objects using the old method, but with the ES6 update, inheritance is much easier and simpler!

Steps to Inherit the Classes : 

First, let us create our parent class.

class Parent{
	constructor(name, age) {
		this.name = name;
		this.age = age;
	}
}

JavaScript

Now let’s create our child class and inherit it with the parent class

//while inheriting the classes we need to use extend word, which basically extends the       class further

class Child extends Parent{
	constructor(name, age){
		//super is a function that uses the parent class's constructor!
		super(name, age);
	}
	sentence(){
		console.log(`Your name is ${this.name} and You're ${this.age} years old`;)
	}
}

JavaScript

Dry run

const child = new Child('meer', 19);
console.log(child.sentence())

//output -> Your name is meer and You're 19 years old

JavaScript
