概要
ES2024では、配列の要素をグループ分けしたマップを作成する
Map.groupBy静的メソッドが追加されています。Map.groupBy静的メソッドはObject.groupBy静的メソッドとよく似たメソッドです。Object.groupBy静的メソッドは配列からオブジェクトを作成するのに対して、Map.groupBy静的メソッドは配列からマップを作成します。Map.groupBy静的メソッドも元々は、Array.prototype.groupToMapメソッドという配列のメソッドとして提案されていましたが、Object.groupBy静的メソッドに合わせる形でMap.groupBy静的メソッドに変更されました。変更されたページ
