JS functions

Hi again!

Why is this code printing undefined at the end?

const alienShip = {
    // A function called invade with arguments brackets
    invade() {
        // This is not printed to the console because this method happens within alienShip
        console.log('Hello! We have come to dominate your planet. Instead of Earth, it shall be called New Xaculon.');
    }
};
console.log(alienShip.invade());
// Hello! We have come to dominate your planet. Instead of Earth, it shall be called New Xaculon.
// undefined

const alienShip = {
    // A function called invade with arguments brackets
    invade() {
        // This is not printed to the console because this method happens within alienShip
        console.log('Hello! We have come to dominate your planet. Instead of Earth, it shall be called New Xaculon.');
    }
};
console.log(alienShip.invade());
// Hello! We have come to dominate your planet. Instead of Earth, it shall be called New Xaculon.
// undefined

The 'Hello ...' text is printed first, then underneath undefined is printed. I really don't understand what is not defined in this code.
