In this activity, you will make a cats object and a dogs object, each with three keys.
Make a dogs object with three keys:
First key called raining with a value of true.
Second key called noise with a value of “Woof!”
Third key called “akeNoise” which contains a function that console.logs the noise to the screen if it is raining dogs.
Next, make a cats object with three keys:
First key called raining with a value of false.
Second key called noise with a value of “Meow!”
Third key called makeNoise which contains a function that console.logs the noise to the screen if it is raining cats.
Make the dog bark.
Make the cat meow.
Create a function called massHysteria that takes in both the cats and the dogs objects and prints “DOGS AND CATS LIVING TOGETHER! MASS HYSTERIA!” if both of the raining keys are equal to true.
See if there is any way to further optimize your code.
// Creates an object and sets it to "dogs"
const dogs = {
// creates the property "raining" and sets it to true
raining: true,
// Creates the property "noise" and sets it to "Woof!"
noise: "Woof!",
// Creates the method "makeNoise", which when called, prints dogs.noise if .raining is true
makeNoise() {
// The 'this' keyword refers to the object it's called from
// i.e. this.raining refers to the raining property of 'this' particular object
if (this.raining === true) {
console.log(this.noise);
}
}
};
// Creates an object and sets it to "cats"
const cats = {
raining: false,
noise: "Meow!",
makeNoise() {
if (this.raining === true) {
console.log(this.noise);
}
}
};
// Calls the "makeNoise" methods for both objects
dogs.makeNoise();
cats.raining = true;
cats.makeNoise();
// Creates a function called "massHysteria" which takes in both objects and
// Prints a message to the screen if ".raining" is true for both of them
const massHysteria = (dogs, cats) => {
if (dogs.raining === true && cats.raining === true) {
console.log("DOGS AND CATS LIVING TOGETHER! MASS HYSTERIA!");
}
};
massHysteria(dogs, cats);
