【JS】複数のオブジェクトを持つ配列を、特定の要素の昇順に並び替える

Last updated at Posted at 2022-10-24

タイトルの通りですが、以下の配列をscoreの値の昇順に並び替えています。

let arr = [
  {name: "John", score: 80},
  {name: "Mike", score: 60},
  {name: "Beth", score: 70}
];


let sorted  = arr.sort(function(a, b) {
  return a.score - b.score;
});

注意ですが、配列の中に複数のオブジェクトがある形の場合のみ、今回の方法でソートできます。

オブジェクトの中に複数オブジェクトがあり、それを並べ替えたい場合はほんの少しやり方が変わります。
