合并Node js中的两个对象数组

Question

输入：

const name = [{id:1, first_name: "Sade", age:"30"}, {id:2, first_name: "Jon", age:"40"}];
const ln = [{last_name: "Smith"}, {last_name: "Doe"}];

输出：

const name = [
{id:1, first_name: "Sade", last_name: "Smith", age:"30"},
{id:2, first_name: "Jon", last_name: "Doe", age"40"}
];

请帮助我在nodejs 中获得此输出

Answer 1

您可以使用.map()和Spread Syntax来获得所需的输出：

const name = [{id:1, first_name: "Sade"}, {id:2, first_name: "Jon"}];
const lname = [{last_name: "Smith"}, {last_name: "Doe"}];
const output = name.map((o, i) => ({...o, ...lname[i]}));
console.log(output);

.as-console-wrapper { max-height: 100% !important; top: 0; }
