javascript - 合并数组到对象数组 JavaScript

Question

我这里有一个数组:

var array = [
    [
        ['firstName', 'Nork'], ['lastName', 'James'], ['age', 22], ['position', 'writer']
    ],
    [
        ['firstName', 'James'], ['lastName', 'Rodel'], ['age', 25], ['position', 'programmer']
    ]
];

我创建了一个函数，它将我的函数转换为 obj 数组，如下所示:

[
    {firstName: 'Nork', lastName: 'James', age: 22, position: 'writer'},
    {firstName: 'James', lastName: 'Rodel', age: 25, role: 'programmer'}
]

所以我创建了一个函数来执行此操作。但是我不确定从哪里开始才能合并它们。

function changeData(array) {
  var obj = { };

}

changeData(array);

有什么帮助吗？

使用[].map在 [].reduce

---

The map() method creates a new array with the results of calling a provided function on every element in this array.

---

The reduce() method applies a function against an accumulator and each element in the array (from left to right) to reduce it to a single value.

var array = [
  [
    ['firstName', 'Nork'],
    ['lastName', 'James'],
    ['age', 22],
    ['position', 'writer']
  ],
  [
    ['firstName', 'James'],
    ['lastName', 'Rodel'],
    ['age', 25],
    ['position', 'programmer']
  ]
];

function mergeObjectArray(array) {
  return array.map(function(el) {
    return el.reduce(function(a, b) {
      a[b[0]] = b[1];
      return a;
    }, {})
  });
}
console.log(mergeObjectArray(array));
