    console.log(item);
  });
});

const animal = {
    canJump: true
};
const bird = Object.create(animal);

bird.canFly = true;

bird.hasFeathers = true;

function birdCan() {
    for (value of Object.keys(bird)) {
        console.log(value + ":" + " " + bird[value])
    }
}
// Task 3
function animalCan() {
    for (props in bird) {
        console.log(`${props}: ${bird[props]}`);
    }
}
logDairy();
birdCan();
animalCan()
