从嵌套的 json 创建一个对象

Question

我有以下 json 从我的服务器以角度接收，我想从这个 Json 创建一个自定义对象

{
    "showsHall": [
        {
            "movies": [
                "5b428ceb9d5b8e4228d14225",
                "5b428d229d5b8e4228d14226",
            ],
            "shows": [
                "5b428d6b9d5b8e4228d14229",
                "5b428ef69d5b8e4228d1422a",
            ],
            "_id": "5b428d439d5b8e4228d14228",
            "hallName": "Small hall",
            "rows": 10,
            "seats": 40,
        }
    ],
    "movie": [
        {
            "showsHalls": [
                "5b428d439d5b8e4228d14228",
                "5b43490592bd380e30fef376"
            ],
            "shows": [
                "5b428d6b9d5b8e4228d14229",
                "5b466d9d75a55841c48bacfc"
            ],
            "_id": "5b428ceb9d5b8e4228d14225",
            "movieName": "Moonwalker - Michael jackson",
            "directorName": "Jerry Kramer, Colin Chilvers",
            "movieDescription": "Anthology movie by, and starring, Michael 
             Jackson in his prime, combining a number of...",
        }
    ],
    "takenSeats": [],
    "_id": "5b428d6b9d5b8e4228d14229",
    "showDate": "7/10/2018",
    "showStartTime": "4:00 PM",
    "showEndTime": "6:00 PM",
}

我想要得到的结果应该是：

{       
        "hallName": "Small hall",
        "movieName": "Moonwalker - Michael jackson" 
        "takenSeats": [],
        "_id": "5b428d6b9d5b8e4228d14229",
        "showDate": "7/10/2018",
        "showStartTime": "4:00 PM",
        "showEndTime": "6:00 PM",
}

任何帮助将不胜感激，谢谢

假设您的原始对象名为source，您可以按如下方式组装新对象：

 const newObject = {       
    "hallName": source.showsHall[0].hallName,
    "movieName": source.movie[0].movieName,
    "takenSeats": source.takenSeats,
    "_id": source._id,
    "showDate": source.showDate,
    "showStartTime": source.showStartTime,
    "showEndTime": source.showEndTime
}

// have a look at it
console.log(newObject);
