Inheritance is an important concept in Object Oriented Programming.
Inheritance is the process whereby one class, also called the sub-class, acquires the properties and methods of another class, also known as the super class.
To create a class inheritance in Javascript, we use the “extends” keyword.
class Animal{
constructor(name){
this.name = name;
}
sound(){
console.log(`${this.name} makes sound`)
}
}
class Cat extends Animal{
myCat(){
super.sound()
}
}
let cat = new Cat("Fuzzy");
console.log(cat.myCat()); //Fuzzy makes soundNotice that we use the “super” keyword to access the method from the parent class.
The class “Cat” now acquires the method of the super class “Animal”
