根据JavaScript中的键/值对将对象拆分为对象数组的最小方法是什么？

Question

我有了这个对象：

var obj = { 
    family : [{name: 'will', age: 30}, {name: 'husain', age: 12}], 
    friends : [{name: 'cody', age: 31}, {name: 'jeff', age: 11}], 
    school : [{name: 'daniel', age: 20}, {name: 'carl', age: 15}] 
} 

其转换成该

var obj = [ 
    {family : [{name: 'will', age: 30}, {name: 'husain', age: 12}]}, 
    {friends : [{name: 'cody', age: 31}, {name: 'jeff', age: 11}]}, 
    {school : [{name: 'daniel', age: 20}, {name: 'carl', age: 15}]} 
]; 

写我现在用for..in建立一个新的数组，并与主要作为新对象等重点创建对象上。

我这样做是正确的，现在

var arr = []; 

for (let key in obj) { 
    arr.push({key: obj[key]}) 
} 

Answer 1

我觉得Object.keys是最好的选择：

var obj = { 
 
    family : [{name: 'will', age: 30}, {name: 'husain', age: 12}], 
 
    friends : [{name: 'cody', age: 31}, {name: 'jeff', age: 11}], 
 
    school : [{name: 'daniel', age: 20}, {name: 'carl', age: 15}] 
 
} 
 
var r = Object.keys(obj).map(x => ({[x]: obj[x]})) 
 

 
console.log(r)
