No dark magic or coquettish operations. Just go through the b in the attribute and generate a new object

.

there is no dark magic, but it is not troublesome to implement it with es6 

const arr = {
  opinionVO: [
    {a: '', b: '1,2,3', c: 10047},
    {a: '', b: '4,5,6', c: 10047},
  ],
};

const result = {
  ...arr,
  opinionVO: arr.opinionVO.reduce((res, item) => res.concat(...item.b.split(',').map(b => ({...item, b}))), []),
};

console.log(result)
