for 循环创建额外的数组作为回报答案

【问题描述】：

我正在尝试将数据推送到一个数组中并在一个对象中返回两个数组。这些数据的形状真的让我很难过......我试图返回的是这样的：

{
associates: [{...},{...}],
 telehealth: [{...},{...}] 
}

但相反，我得到的嵌套数组为每种类型返回了一个额外的空数组。这是一个工作示例，任何对此的建议将不胜感激。这些数据的形状真的让我很难过......：

const activeTab = "Physicians"
const NEWRATES = {
  standard: [
    {
      "ORG A": {
        Physicians: {
          telehealth: {
            orgName: "ORG A",
            weekdayEncounters: 15,
            weeknightEncounters: 16.25,
            weekendDayEncounters: 16.25,
            weekendNightEncounters: 97.25,
            holidayEncounters: 17.25,
            stipend: 0,
          },
        },
        NonPhysicians: {
          telehealth: {

【解决方案1】：

Map 返回数组，由每次迭代返回的项目组成。这就是为什么你有数组的原因。

只需在上述范围内移动两个列表并使用forEach。

const sortData = Object.values(NEWRATES);
const NEWfiltered = !!NEWRATES && sortData;
const associatesList = [];
const telehealthList = [];
!!NEWfiltered &&
    NEWfiltered.forEach((item, idx) => {
        for (let i = 0; i < item.length; i++) {
            let orgKeys = Object.keys(item[i]).toString();
            let org = item[i][orgKeys];
            // if the object org.Physicians and the type is telehealth push into the array
            if (!org.ltc && org[activeTab]) {
                telehealthList.push(org[activeTab].telehealth);
            } else if (!!org.ltc && org[activeTab]) {
                associatesList.push(org[activeTab].associates);
            }
        }
    });
console.log({ associatesList, telehealthList }, "NEWRATES:");
```javascript
