对两个对象数组的数据求和

我有两个对象数组，我想对具有相同键（在本例中为 id）的对象求和，如果没有匹配键，则只需创建一个新的。如果我是，我很抱歉没有解释清楚，我对 JavaScript/Array/Object 很陌生......

var dataOne = [ { id:"1", total: 10, win: 5 }, { id:"2", total: 5, win: 1 }, { id:"3", total: 5, win: 2 } ]

and

var dataTwo = [ { id:"1", total: 5, win: 2 }, { id:"2", total: 2, win: 3 }, { id:"5", total: 5, win: 4 } ]

预期结果：

var combinedData = [ { id:"1", total: 15, win: 7 }, { id:"2", total: 7, win: 4 }, { id:"3", total: 5, win: 2 }, { id:"5", total: 5, win: 4 } ]

我尝试使用来自的解决方案将对象数组中的所有数据求和到新的对象数组中 https://stackoverflow.com/questions/52479107/sum-all-data-in-array-of-objects-into-new-array-of-objects但是，显然数据类型有点不同

所以，我尝试使用这种方法Javascript - 具有相同属性的两个对象的总和 https://stackoverflow.com/questions/42488048/javascript-sum-of-two-object-with-same-properties

 function sumObjectsByKey(...objs) {
      for (var prop in n) {
        if (acc.hasOwnProperty(prop)) acc[prop] += n[prop];
        else acc[prop] = n[prop];
      }
      return acc;
    }

and

var combinedData = sumObjectsByKey(dataOne, dataTwo);

但显然，该方法不适用于对象数组。 我明白了

{0: "0[object Object][object Object]", 1: "0[object Object][object Object]", 2: "0[object Object][object Object]"}

因此。

使用剩余参数组合两者并Array.flat()。将项目缩减为 Map，同时将当前项目与 Map 中已存在的项目组合起来。转换Map.values()数组的迭代器Array.from():

const sumObjectsByKey = (sumFn, ...arrs) => Array.from(
  arrs.flat() // combine the arrays
  .reduce((m, o) => // retuce the combined arrays to a Map
    m.set(o.id, // if add the item to the Map
      m.has(o.id) ? sumFn(m.get(o.id), o) : { ...o } // if the item exists in Map, sum the current item with the one in the Map. If not, add a clone of the current item to the Map
    )
  , new Map).values()
)

// utility function to sum to object values (without the id)
const sumItem = ({ id, ...a }, b) => ({
  id,
  ...Object.keys(a)
    .reduce((r, k) => ({ ...r, [k]: a[k] + b[k] }), {})
});

const dataOne = [ { id:"1", total: 10, win: 5 }, { id:"2", total: 5, win: 1 }, { id:"3", total: 5, win: 2 } ]
const dataTwo = [ { id:"1", total: 5, win: 2 }, { id:"2", total: 2, win: 3 }, { id:"5", total: 5, win: 4 } ]

const result = sumObjectsByKey(sumItem, dataOne, dataTwo)
  
console.log(result)
