如何在js中计算一个对象每2个值的总和

How to calculate sum of an object each 2 its value in js

我有一个这样的对象,我如何计算代码和codePrev的总值:

{
    "code01Prev": 3756743628,
    "code01": 10346000,
    "code02Prev": 0,
    "code02": 0,
    "code10Prev": 3756743628,
    "code10": 10346000,
    "code11Prev": 0,
    "code11": 0,
    "code20Prev": 3756743628,
    "code20": 10346000
}

选择普通香草。该代码有点强制性(不解释是什么,而是如何解释)。如果可能,最好考虑更改数据结构。

data = {
    code01Prev: 3756743628,
    code01: 10346000,
    code02Prev: 0,
    code02: 0,
    code10Prev: 3756743628,
    code10: 10346000,
    code11Prev: 0,
    code11: 0,
    code20Prev: 3756743628,
    code20: 10346000
}

initialTotals = {
  code: 0,
  codePrev: 0}
    
dataKeyValues = Object.entries(data)    

totals = dataKeyValues.reduce(
  (totalAccumulated, [key, value]) => {
    if (key.endsWith('Prev')){
      return {
        ...totalAccumulated,
        codePrev: totalAccumulated.codePrev + value}}
    return {
      ...totalAccumulated,
      code: totalAccumulated.code + value}},
  initialTotals)

console.log(totals)

// totals:
// {
//   "code": 31038000,
//   "codePrev": 11270230884
// }
