Merge Array to Object Array JavaScript

Question

I have an array here:

var array = [
    [
        [\'firstName\', \'Nork\'], [\'lastName\', \'James\'], [\'age\', 22], [\'position\', \'writer\']
    ],
    [
           


        

Answer 1

Use [].map over [].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));
