jsでもifやswitchを式として扱いたい

Last updated at Posted at 2020-09-23

忘れない内にメモ
こうすれば行ける

const result = ((some) => {
    if(some === 1) {
        return 1;
    } else {
        return 2;
    }
})(some);
const result = ((some) => {
    switch(some) {
        case 1:
            return 1;
        case 2:
            return 2;
        default:
            return 3;
    }
})(some);

ifじゃなくて三項演算子使うのもアリか
