Javascript 配列・連想配列

Last updated at Posted at 2024-03-16

Javascript の勉強した内容のメモ書きをしていく

配列の場合、インデックス番号指定でデータを取得する。

配列
const dog = [
    '秋田犬',
    'ポメラニアン',
];

console.log(dog[1]);

連想配列の場合、メンバー毎にドット(.)で区切り、欲しいデータを取得する。

連想配列
const dog = {
    '秋田犬':{
        'color':'茶色',
        'size':'big'
    },
    'ポメラニアン':{
        'color':'茶色',
        'size':'mini'
    }
};

console.log(dog.ポメラニアン.size);
