根据 javascript 中的键名过滤对象数组

Question

我有如下对象数组

 employees = [
    {name: "Tony Stark", department: "IT"},

    {name: "Peter Parker", department: "Pizza Delivery"},


    {name: "Bruce Wayne", department: "IT"},

    {name: "Clark Kent", department: "Editing"}
];

我想像

一样过滤对象数组

 employees = [
    {name: "Tony Stark"},

    {name: "Peter Parker"},


    {name: "Bruce Wayne"},

    {name: "Clark Kent"}
];

Answer 1

你可以使用 map()

const employees = [
  { name: "Tony Stark", department: "IT" },
  { name: "Peter Parker", department: "Pizza Delivery" },
  { name: "Bruce Wayne", department: "IT" },
  { name: "Clark Kent", department: "Editing" }
];

const result = employees.map(({ name }) => ({ name }));

console.log(result);

const employees = [
  { name: "Tony Stark", department: "IT" },
  { name: "Peter Parker", department: "Pizza Delivery" },
  { name: "Bruce Wayne", department: "IT" },
  { name: "Clark Kent", department: "Editing" }
];

const result = employees.map((employee) => { 
  return { 
    name: employee.name 
  }
});

console.log(result);
