【问题描述】：
我已经为 FreecodeCamp 构建了以下项目。
我的项目必须保存用户姓名和锻炼以及比赛时间（包括日期）。
我的问题是访问日期的集体数据数组，并且只返回日期和练习匹配 url 中的查询。
这是我返回的 JSON 代码。我只需要设置限制日期并练习匹配用户在 url 中的查询设置的查询，以返回匹配 2018-11-22T00:00:00.000Z 的日期数量（例如 localhost:3000/addme16?id=5_OYzu1QG&start=22 November 2018&end=22 November 2018&limit=2）。因此，如果查询限制设置为两个日期并返回要返回的练习，则仅返回与 2018-11-22T00:00:00.000Z 匹配的两个日期对象。
{
"_id": "5_OYzu1QG",
"username": "Timmy",
"data": [{
"description": "walking",
"duration": 1,
"date": "2018-11-22T00:00:00.000Z"
},
{
"description": "Reading",
"duration": 2,
"date": "2019-01-01T00:00:00.000Z"
},
{
"description": "Mountain Biking",
"duration": 3,
"date": "2019-01-22T00:00:00.000Z"
}
],
"__v": 0
}我忘记添加我的架构和将查询字符串日期更改为 iso 对象日期的方法。这是我的额外代码信息，显示了我如何向我的用户数据添加练习。我只想返回与数据库中iso数据查询日期匹配的日期
