javascript - 根据项目要求将json对象数组解析为特定格式的json数组

Question

根据我项目中的要求，我得到以下 json 数组作为输入，但我需要将其转换为特定格式的 json 对象数组。

[
  {
    "accident_description": "bike accident",
    "reported_by": "john",

  },
   {
    "accident_description": "car accident",
    "reported_by": "sam",

  }
]

输出>>>

  "fields": [
    {
      "title": "accident_description",
      "values": "bike accident"
      "type": "generic",

    },
    {
      "title": "reported_by",
      "values": "john",
      "type": "generic",

    },
    {
      "title": "accident_description",
      "values": "car accident"
      "type": "generic",

    },
    {
      "title": "reported_by",
      "values": "sam",
      "type": "generic",

    },
  ]

您可以使用reduce函数来获得所需的输出:-

[
  {
    "accident_description": "bike accident",
    "reported_by": "john",

  },
   {
    "accident_description": "car accident",
    "reported_by": "sam",

  }
].reduce((arr,item) => {
    for(let key in item){
        arr.push({
            "title" : key,
            "values" : item[key],
            "type"  : "generic"
        });
    }
    return arr;

},[]);
