以 JSON 格式打印数组元素

  • 772

我们有一个数组名称

let name = [
    ['Ободович', 'Иван'],['Булий' , 'Андрей'],['Булий', 'Андрей']
]

let res = name.forEach((elem) => {
let data = Object.create(null, {lastName: {value:''}, firstName: {value:''}) 
data.lastName = elem[0];
data.firstName = elem[1]
})
console.log(res)

期待

res = [
    {lastName:'Ободович', firstName:'Иван'},
    {lastName:'Булий', firstName:'Андрей'},
    {lastName:'Булий', firstName:'Андрей'}
]
javascript

    forEach()方法不返回任何内容。使用map()方法

    let name = [
  ['Ободович', 'Иван'],
  ['Булий', 'Андрей'],
  ['Булий', 'Андрей']
];

const res = name.map(item => ({
  lastName: item[0],
  firstName: item[1]
}));
console.log(res);
