console.log(Car.prototype.isPrototypeOf(Car));

console.log(Car.prototype.isPrototypeOf(car));

**Question 1:** Guess the**Output** and Explain Why?

functioncarObject(name,model) {

let car=Object.create(constructorObject);

car.name= name;

car.model= model;

this.engineMethod=function(){

console.log("This is engine method of car")

}

return car;

}

let constructorObject= {

speak:function(){

}

}

let myCar=carObject("Audi",2023);

console.log(myCar.__proto__);

**Question 2:** You have given an example of**OOP** Code. Your task is to explain the use of**super** keyword in**Dogs** class.

And You have to**refactor** the code again after removing**super** keyword from the**Dogs** class(You have remove those lines/statements which are not**necessary** after**removing** super**keyword**)

classAnimals {

constructor(name,age) {

this.name= name;

this.age= age;

}

sing() {

return`${this.name} can sing`;

}

dance() {

return`${this.name} can dance`;

}

}

classDogsextendsAnimals {

constructor(name,age,whiskerColor) {

super(name, age);

this.whiskerColor= whiskerColor;

}

whiskers() {

return`I have${this.whiskerColor} whiskers`;

}

}

let newDog=newDogs("Clara",33,"indigo");

console.log(newDog)

**Question 3:** What are the advantages of using**getter** and**setter** method in OOP?

**Question 4:** You have OOP code below. And there is**single** error in this code? Your task is to**remove that error**.

**Important Note**: To solve this error You need to know about**method chaining** concept.

classCar {

constructor(id){

this.id= id;

}

setMake(make) {

this.make= make;

}

setModel(model) {

this.model= model

}

setFuelType(fuelType) {

this.fuelType= fuelType;

}

getCarInfo() {

return {

"id":this.id,

"make":this.make,

"model":this.model,

"fuelType":this.fuelType

};

}}

console.log(

newCar(233)

.setMake("Honda")

.setModel("Civic")

.setFuelType("Petrol")

.getCarInfo()

);

**Question 5:** What is difference between__ proto__ and prototype property of Object? Explain with**Example**?

**Question 6:** create class of**Person** with properties name, age.

Your main task is to add**static** method in that class of your choice ( e.g brainMethod)

classPerson {

constructor(name,age){

this.name= name;

this.age= age;

}

}

let me=newPerson("abhishek",25);

console.log(me)
