javascript - 遍历对象数组并输出自定义对象

我需要从Typescript中的对象数组构建自定义对象。

在下面的给出示例中，如何计算Salesman_1_name在数组中的次数，为每个Salesman_1_name加上毛额，并计算每个Salesman_1_name的保修是否不为空？所以，如果我有：

[
    {salesman_1_name:Brian, gross:100, warranty: Easycare},
    {salesman_1_name:Brian, gross:100, warranty: Easycare},
    {salesman_1_name:Brian, gross:100, warranty: null},
    {salesman_1_name:Kreso, gross:100, warranty: null},
    {salesman_1_name:Filip, gross:100, warranty: Easycare}
]

我需要输出：

[
    Name:Brian, Count:3, Gross:300, WarrantyCount:2,
    Name:Kreso, Count:1, Gross:100, WarrantyCount:0,
    Name:Filip, Count:1, Gross:100, WarrantyCount:1
]

最佳答案

data.reduce((acc, cur) => {
  const obj = acc.find(x => x.Name === cur.salesman_1_name);
  if (obj) {
    obj.Gross += cur.gross;
    obj.WarrantyCount = cur.warranty !== null ? obj.WarrantyCount + 1 : obj.WarrantyCount;
  } else {
    acc.push({ Name: cur.salesman_1_name, Gross: cur.gross, WarrantyCount: cur.warranty !== null ? 1 : 0 });
  }
  return acc;
}, []);
