Cat Life

function catLife(input) {
    let catBreed = input[0];
    let catGender = input[1];

    let breedYears = 0;

    switch (catBreed) {
        case "British Shorthair":
            breedYears = 13;
            break;

        default:
            console.log(`${catBreed} is invalid cat!`);
            break;
    }

    if (catGender === "f") {
        breedYears++;

    }
}



Фундаменталс решение:

function catLife([catBreed, catGender]) {

    let breedYears = {
        "Siberian": 11,
        "American Shorthair": 12,
        "British Shorthair": 13,
        "Persian": 14,
        "Siamese": 15,
        "Ragdoll": 16
    }[catBreed];

    catGender === "f" ? breedYears++ : breedYears;

    console.log(breedYears > 1 ? `${breedYears * 2} cat months` : `${catBreed} is invalid cat!`);

}
