json数据组装

Question

如何将这数据组装成：
expensedate：5月 amout:10 20 30

Answer 1

var data = {
  neibie1: [
    {
      expensedate: '6月',
      amount: 40
    },
    {
      expensedate: '6月',
      amount: 30
    },
    {
      expensedate: '5月',
      amount: 10
    },
    {
      expensedate: '5月',
      amount: 60
    },
  ]
}


console.log(Object.values(data.neibie1.reduce((res, item) => {
  var ex = res[item.expensedate]
  if(ex) {
    ex.amount.push(item.amount)
  } else {
    res[item.expensedate] = {
      expensedate: item.expensedate,
      amount: [item.amount]
    }
  }
  return res;
}, {})))

提问题不要只贴图，那么长串数据要回答的人手打？
