將javascript對象轉換爲具有特定順序的數組

Question

如何將JavaScript對象轉換爲對象數組？數組元素必須由index財產的原始對象進行排序：

輸入：

var o = { 
    "0gfbpa1508024708952": { 
    title: "hi daughter", 
    index: 3 
    }, 
    "b8tl5k1508024741100": { 
    title: "hi dad", 
    index: 0 
    }, 
    "cxr9x1508024697320": { 
    title: "hi son", 
    index: 2 
    }, 
    "qua2802469732": { 
    title: "hi cousin", 
    index: 9007199254740991 
    }, 
    "tck80i1508024731561": { 
    title: "hi mom", 
    index: 1 
    } 
}; 

輸出：

[ 
    {id: "b8tl5k1508024741100", title: "hi dad"},  // array index 0 
    {id: "tck80i1508024731561", title: "hi mom"},  // array index 1 
    {id: "cxr9x1508024697320", title: "hi son"},   // array index 2 
    {id: "0gfbpa1508024708952", title: "hi daughter"}, // array index 3 
    {id: "qua2802469732", title: "hi cousin"}   // array index 4 
] 

This question只與訂貨有助於/的排序陣列。它沒有解釋如何（1）將對象鍵轉換爲數組對象id屬性，以及（2）如何從數組中刪除index鍵。這裏正在進行轉型，而不僅僅是基於對象鍵的排序/排序。

let o = { 
    "0gfbpa1508024708952": { 
    title: "hi daughter", 
    index: 3 
    }, 
    "b8tl5k1508024741100": { 
    title: "hi dad", 
    index: 0 
    }, 
    "cxr9x1508024697320": { 
    title: "hi son", 
    index: 2 
    }, 
    "qua2802469732": { 
    title: "hi cousin", 
    index: 9007199254740991 
    }, 
    "tck80i1508024731561": { 
    title: "hi mom", 
    index: 1 
    } 
}, 
arr = []; 


for (let k in o) { 
    let tmp = o[k]; 
    tmp.id = k; 
    arr.push(tmp); 
} 
arr.sort(function(a,b) { return a.index - b.index; }); 

for (let k in arr) 
    delete arr[k].index;
