如何使用數組解構提取嵌套的 object 屬性？

Question

我使用此代碼未定義：

 const json = {"records":[{"recordid":"1694119","recordindex":1,"status":"updated successfully"}],"message":{"returncode":1}}; const { records: {status} } = json; console.log(status);

如何獲得預期的：“更新成功”？

Answer 1

由於records是一個數組，所以需要加上括號：

 const json = {"records":[{"recordid":"1694119","recordindex":1,"status":"updated successfully"}],"message":{"returncode":1}}; const { records: [{status}] } = json; console.log(status);
