JavaScriptで2次元配列のindexを取得する

Posted at

いきなりですがタイトル詐欺です。JavaScriptに多次元配列は定義されていませんが他に良い表現方法が見つからなかったのでこのような表記にしました。

サンプルコード
var hoge = [
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9]
];

hoge.forEach( (row, i) => {
    row.forEach( (element, j) => {
        if(element === 6) {
            console.log(i, j)  // 1,2
        }
    })
});

もうちょっとマシなタイトルがあればコメントください。
