    return prefs.find((pref) => pref.code === Number(value));
}
function filterByArea(value) {
    return prefs.filter((pref) => pref.area === value);
}
function prefectures() {
    return prefs;
}
function prefectureCodes() {
    return prefs.map((pref) => pref.code);
}
function prefectureNames() {
    return prefs.map((pref) => pref.name);
}
function prefectureEnNames() {
    return prefs.map((pref) => pref.enName);
}
function prefectureAreas() {
    const onlyUnique = (value, index, self) => {
        return self.indexOf(value) === index;
    };
    const areas = prefs.map((pref) => pref.area);
    return areas.filter(onlyUnique);
}
function prefectureCapitals() {
    return prefs.map((pref) => pref.capital);
}
export { findByName, findByCode, filterByArea, prefectures, prefectureCodes, prefectureNames, prefectureEnNames, prefectureAreas, prefectureCapitals, };
