javascript - JS - 在其中一个对象上添加新属性和值

Question

我有一个对象列表

const array = [
    {club: "Club A", number: 12},
    {club: "Club B", number: 12}
]

我想在其中一个对象中添加新属性

member: ["a", "b"]

这将是

const newArray = [
    {club: "Club A", number: 12, member: ["a", "b"]},
    {club: "Club B", number: 12}
]

尝试使用 map

const newArray = array.map(obj => check if obj.club ==="Club A" )

Answer 1

您可以使用map和 object destrcturing

const array = [{club: "Club A", number: 12},{club: "Club B", number: 12}]
let member = ["a", "b"]

const newArray = array.map(obj => obj.club === "Club A" ? {...obj,member} : obj)

console.log(newArray)
