javascript - 如何在 typescript 中分隔具有特定数组前缀的对象数组

Question

我计划通过使用索引规范分离那些类型的数组来准备这个数组

默认数据格式

[{
      "Emp_code": "EM-00001",
      "Emp_title": "11",
      "Emp_firstName": "22",
      "Emp_lastName": "33",
      "Emp_dateOfBirth": "20-10-1985",
      "Con_title": "title",
      "Con_email": "email",
      "Con_addres": "address",
      "Con_phone": "phone"
    }]

所需格式

[{
  "emp": {
      "code": "EM-00001",
      "title": "11",
      "firstName": "22",
      "lastName": "33",
      "dateOfBirth": "20-10-1985",
  },
  "con": {
      "Con_title": "title",
      "Con_email": "email",
      "Con_addres": "address",
      "Con_phone": "phone"
  }
}]

您可以将属性名称简化为 [{ emp: {} }, { con: {} }] 的起始累加器，并且每次迭代您都可以将属性添加到累加器中的相应项。

const data = [{
      "Emp_code": "EM-00001",
      "Emp_title": "11",
      "Emp_firstName": "22",
      "Emp_lastName": "33",
      "Emp_dateOfBirth": "20-10-1985",
      "Con_title": "title",
      "Con_email": "email",
      "Con_addres": "address",
      "Con_phone": "phone"
    }];
    
const format = obj =>
  Object.getOwnPropertyNames(obj[0]).reduce(
    (acc, prop) => {
      if (prop.startsWith('Emp_')) {
        acc[0].emp[prop.replace('Emp_', '')] = obj[0][prop];
      } else {
        acc[1].con[prop] = obj[0][prop];
      }
      return acc;
    },
    [{ emp: {} }, { con: {} }]
  );
 
 console.log(format(data));
