You can do it with a single line:

const newResult = list.map(a => a.map(([k,v]) => ({[k]: v})));

const show = msg => {console.log(JSON.stringify(msg));};
const list = [
  [
    ['itemCode', 1],
    ['item', 'Pen'],
    ['cashier', 'Sam']
  ],
  [
    ['itemCode', 2],
    ['item', 'Eraser'],
    ['cashier', 'Kim']
  ]
];

const newResult = list.map(a => a.map(([k,v]) => ({[k]: v})));
show(newResult);
