根据键合并两个对象数组

问题描述：

我有两个数组：

数组1：

[
  { id: "abdc4051", date: "2017-01-24" }, 
  { id: "abdc4052", date: "2017-01-22" }
]

和数组2：

[
  { id: "abdc4051", name: "ab" },
  { id: "abdc4052", name: "abc" }
]

我需要根据 id 合并这两个数组，得到这个：

I need to merge these two arrays based on id and get this:

[
  { id: "abdc4051", date: "2017-01-24", name: "ab" },
  { id: "abdc4052", date: "2017-01-22", name: "abc" }
]

如何在不迭代的情况下执行此操作 Object.keys ？

How can I do this without iterating trough Object.keys?

答

你可以这样做，

let arr3 = [];
arr1.forEach((itm, i) => {
  arr3.push(Object.assign({}, itm, arr2[i]));
});

console.log(arr3); // you will get the merged array.
