Questions

Please check the JS Console for the output to the following questions

1. Find total number of areas in the house:

                
                    let houseAreas = Object.keys(house.areas[0]).length;
                    console.log(houseAreas);
                
            

2. Add a dining table to the living room:

                
                    house.areas[0].livingRoom.items.push("dining table");
                    console.log(house.areas[0].livingRoom.items);
                
            

3. Add a stove to the kitchen:

                
                    house.areas[0].kitchen.items.push("stove");
                    console.log(house.areas[0].kitchen.items);
                
            

4. Remove the washing machine from bedroomOne:

                
                    house.areas[0].bedroomOne.items.pop();
                    console.log(house.areas[0].bedroomOne.items);
                
            

5. Find the total number of beds in all rooms:

                
                    let rooms = Object.keys(house.areas[0]);
                    let beds = 0;

                    for (let i = 0; i < rooms.length; i++) {
                        let roomItems = house.areas[0][rooms[i]]["items"];
                        for (let j = 0; j < roomItems.length; j++) {
                            if(roomItems[j] == "bed") {
                                beds++
                            }
                        }     
                    };

                    console.log(beds);

                
            

6. Change the color of the car to blue:

                
                    house.garage.car.color = "blue";
                    console.log(house.garage.car.color);
                
            

7. Add a another car to the garage with a honk function:

                
                    house.garage.car2 = {
                        color: 'green',
                        wheels: 4,
                        honk: ()=>{alert("Beep")}
                    };
                    console.log(house.garage);
                
            

8. Make the new car honk:

                
                    house.garage.car2.honk();
                
            

9. Change the 'broken chair' in the kitchen to 'new chair':

                
                    house.areas[0].kitchen.items.splice(1,1,"new chair");
                    console.log(house.areas[0].kitchen.items);
                
            

10. If the house has a garden, console.log the name of the flower:

                
                    if (house.garden[0]) {
                        console.log(house.garden[1]);
                    };
