javascript - 如何根据多笔费用分摊金额拆分费用给不同份额的多个用户？

Question

我想根据以下条件分摊费用:

1. Expense By user.
2. Divided by users.
3. Share of each user.

我想要输出欠其他用户钱的用户列表。我尝试过以不同的方式进行计算，但没有任何帮助。

如果有人能提供帮助，将不胜感激......

输入Json:

var expenseObj = [
  {
    expenseBy:{
      user:"A",
      amount:1000
    },
    dividedBy: [
      {
        user:"A",
        amount:100
      },{
        user:"B",
        amount:500
      },{
        user:"C",
        amount:400
      }
    ]
  },
  {
    expenseBy:{
      user:"B",
      amount:2000
    },
    dividedBy: [
      {
        user:"A",
        amount:1000
      },{
        user:"B",
        amount:400
      },{
        user:"C",
        amount:600
      }
    ]
  }
]

Answer 1

  for (let i = 0; i<expenseObj.length; i++){
      var share = expenseObj[i].expenseBy.amount/expenseObj[i].dividedBy.length;
      var addedBy = expenseObj[i].expenseBy.user;
      var addedAmount = expenseObj[i].expenseBy.amount;
      for(j=0; j<expenseObj[i].dividedBy.length;j++){
        var amount = share-expenseObj[i].dividedBy[j].amount
          if( amount >= 0){
            console.log(expenseObj[i].dividedBy[j].user+" owes "+amount+" in expense added by "+addedBy+" of amount "+addedAmount);
          }
      }
  }

我希望它能让你对你想做什么有一些基本的了解。
