data用id作为键制作一个哈希映射。

let data = [
        {id: 1, name: "Carl", city: "New York"},
        {id: 2, name: "Anna", city: "New York"},
        {id: 3, name: "Carl", city: "Sydney"}
    ];
let map1 = new Map(data.map(e=>[e.id,e]));
let filterValue = [1, 2];
let output = filterValue.map(e=>map1.get(e));
console.log(output);
