javascript - 对不同集合上匹配 id 的对象数组进行排序

Question

我有一个对象数组

array = [
    {id: 5, name: "Helen", age: 20}, 
    {id: 15, name: "Lucy", age: 30}, 
    {id:7, name: "Carlos", age: 1}
]

然后我有一个类似的数组，但排序不同

arraySorted = [        
    {id: 15, name: "Lucy", age: 2}, 
    {id: 5, name: "Lara", age: 11}, 
    {id:7, name: "Carlos", age: 10}
]

两个数组中对象的 ID 始终匹配，其余属性可能会也可能不会。

我需要按照与 arraySorted 相同的 id 顺序对数组进行排序。

(它也可以在普通的 JavaScript 上完成，lodash 不是必需的，但也许会有用)

参见 Map和 Array.prototype.map()了解更多信息。

// Raw.
const raw = [
    {id: 5, name: "Helen", age: 20}, 
    {id: 15, name: "Lucy", age: 30}, 
    {id:7, name: "Carlos", age: 1}
]

// Sorted.
const sorted = [        
    {id: 15, name: "Lucy", age: 2}, 
    {id: 5, name: "Lara", age: 11}, 
    {id:7, name: "Carlos", age: 10}
]

// Match.
const match = (raw, sorted) => (m => sorted.map(s => m.get(s.id)))(new Map(raw.map(r => [r.id, r])))

// Output.
const output = match(raw, sorted)

// Proof.
console.log(output)
