Javascript 中對象數組的排序鍵

Question

我有一組未按字母順序排序的對象。 我想對這些鍵名進行排序。 有沒有辦法做到這一點？

 const artists = [ {name: "Tupac", year: 1996, age: 25}, {name: "Jayz", year: 2021, age: 48} ] // Looking for Output like this const artists = [ {age: 25, name: "Tupac", year: 1996}, {age: 48, name: "Jayz", year: 2021} ]

Answer 1

以下可能在實踐中起作用。 但有一些警告。 如果您絕對需要保證順序，我相信建議是使用Map或轉換為數組。

 const artists = [ {name: "Tupac", year: 1996, age: 25}, {name: "Jayz", year: 2021, age: 48} ]; const sort_object_keys = (object) => Object.keys(object).sort().reduce( (acc, val) => Object.assign(acc, { [val]: object[val] }), {} ); const result = artists.map(sort_object_keys); console.log(result);
