Javascript 我在下面的数组对象中有数据，希望转换另一个数组对象格式

我的API响应-

我想在下面的甲酸如果位置含空然后考虑0。假设数据的总视图值

 this.geographySeriesData = [
      {
         name: 'India',
         data: [500, 555, 444, 777, 877, 9944, 750],
       },
       {
         name: 'USA',
         data: [10, 1000, 1200, 1000, 1200, 1000, 500],
       }

     ];

您可以使用此代码进行转换。它不是最优的，但非常简单易懂。所需的数据存储在finalResult变量中

const result = {};

const locations = data.map(el => el.location).flat();
locations.forEach(loc => {
    result[loc.country] = [];
});
locations.forEach(loc => {
    result[loc.country].push(loc.total_views);
});

const finalResult = Object.keys(result).map(key => ({ name: key, data: result[key]}));

您可以实现这样的精确格式

countryList = []
countryObject = {}

data.forEach((d) => {
  d.location.forEach((loc) => {
    if(loc.country in countryObject){
      countryViewsList = countryObject[loc.country]
      countryViewsList.push(loc.total_views)
      countryObject[loc.country] = countryViewsList
    } else {
      countryObject = Object.assign(countryObject, {[loc.country]: [loc.total_views]})
    }
  })
})

Object.keys(countryObject).forEach((k)=>{
  countryList.push({
    name: k,
    data: countryObject[k]
  })
})

---

countryList

正是您要求的格式。

您已经试过了吗？如果能直接在这里给我们一些你的测试，那就太好了
