Beginning with JavaScript (functions)

I am the entry level of learning JS and following a tutorial I am given this code

function shouldYouGoToTheLake(weather, waterTemperature) {
if (weather == "sunny") {
    return true;
} else if (waterTemperature >= 20) {
    return true;
} else {
    return false;
}
}

shouldYouGoToTheLake("sunny", 0); // true
shouldYouGoToTheLake("sunny", 10); // true
shouldYouGoToTheLake("cloudy", 25); // true
shouldYouGoToTheLake("cloudy", 18); // false

My question is how do you get a return? It is not enough to write shouldYouGoToTheLake(“sunny”, 0); as visual code studio runs the code without a return. Something is missing.

I did not run try to run all 4 returns in one sequence.

I run only 1 sequence

shouldYouGoToTheLake(“sunny”, 0);
