学習備忘録

aa.js
const Asan = {
  name: 'hoge',
  age: 25,
  weight: 60
};

const fullDate = [Asan['name'], Asan['age'], Asan['weight']];
// これだと['hoge', 25, 60]という配列が代入される

const fullDate = [Asan['name'], Asan['age'], Asan['weight']].join();
// これだと'hoge,25,60'という文字列が代入される。
// なおjoin()はデフォルトでカンマ区切りになる。join(',')と同じ意味。
