Javascript for循环中的UUIDV4未更改值

我试图创建一个函数来生成一个以UUID为键的对象数组，以及一些嵌套对象ID的UUID

每个游戏都将基于我导入到文件中的模拟对象

函数需要一个运动（字符串）和一个数量（数字），运动（字符串）将被分配给一个键，数量（数字）将决定for循环的迭代次数

使用for循环时，嵌套对象ID的UUID在每次迭代中都会被覆盖

const mockGame = require('../mock-game');
const uuidv4 = require('uuid/v4');

function generateMockGames(sport, quantity) {
    let games = []

    for (let i = 0; i < quantity; i++) {
        let game = {}
        let id = uuidv4()

        game[id] = {
            search: mockGame.search,
            query: mockGame.query,
            variables: mockGame.variables,
        }

        game[id].search.eventId = id
        game[id].search.competition.categoryName = sport

        game[id].search.id = id
        game[id].search.competition.categoryName = sport;

        games.push(game);
    }

    return games;
}

const mockFootballGame = generateMockGames('football', 3);

输出为：

您正在将循环中的

mockGame

的子对象指定给条目，而不复制它们。因此，在循环中使用新的uuid覆盖

mockGame.query.id

等，然后将

mockGame.query

对象作为一个整体分配给输出。

Ho关于尝试：

const uuid=require（'uuid'）

然后调用

uuid.v4（）

？谢谢！这就是问题所在
