如何遍歷此對象以獲取新對象？

Question

我對 Javascript 比較陌生，剛剛學習了基本的 for 循環和 for in 循環。 如何遍歷此對象以獲取某些鍵和值？ 對象中有一堆嵌套對象，所以我有點困惑。 我正在考慮使用某種“Object...()”方法，但不確定使用哪種方法。

期望的輸出結果是一個具有給定冠軍鍵的對象，后跟冠軍 id/name = {"266": "Aatrox", "103" : "Ahri"}

下面的示例輸入

 const obj = { name: 'Sam', old: 30, nested: { data: 'ABC', time: '3:15' } } for(let i in obj){ console.log(i); //returns values console.log(obj[i]); //returns keys for(let j in obj[i]){ console.log(j); //returns values of nested 2d level console.log(obj[i][j]); //returns keys of nested 2d level } }
