仅将键添加到现有的json数组

Question

我有一个类似下面的JSON数组。是否可以通过循环遍历每个数组来向每个数组添加键值？我希望数组具有相同的键值。

var r_list = [
    {
      "Column Name": "Name",
      "Value": "Some Name",
      "Some key": "Some Value",
      "Some other key": "Some other Value"
    },
    {
      "Column Name": "Age",
      "Value": 62,
      "Some key": "Some Value",
      "Some other key": "Some other Value"
    },
    {
      "Column Name": "Year",
      "Value": 1957,
      "Some key": "Some Value",
      "Some other key": "Some other Value"
    }
  ]

预期输出：

[
    12345: {
      "Column Name": "Name",
      "Value": "Some Name",
      "Some key": "Some Value",
      "Some other key": "Some other Value"
    },
    12345: {
      "Column Name": "Age",
      "Value": 62,
      "Some key": "Some Value",
      "Some other key": "Some other Value"
    },
    12345: {
      "Column Name": "Year",
      "Value": 1957,
      "Some key": "Some Value",
      "Some other key": "Some other Value"
    }
  ]

我尝试过了。 var final_list = r_list.map(r_list => ({12345: r_list})) 但是结果不完全符合我想要的格式。
