Array of array to object - javascript

Question

I am looping to convert the array of array to object, but the final object has only the last item in the object. I am getting confused because you cant push in an object lik

You have to use one loop to iterate over main array and then run loops to iterate over each array item (which also is an array) to construct object with properties you need. You can use map as main loop to return new array with items constructed inside each iteration. To construct those items you can use forEach:

var list = [
    [
      ['itemCode', 1],
      ['item', 'Pen'],
      ['cashier', 'Sam']
    ],
    [
      ['itemCode', 2],
      ['item', 'Eraser'],
      ['cashier', 'Kim']
    ]
  ];


function result(array) {
   let newArray = array.map(function(nestedArray) {
     let obj = {};
     nestedArray.forEach(function(item) {
       obj[item[0]] = item[1];
     });
     return obj;
     
   });
  return newArray;
}
console.log(result(list));
