In the following data set, I need to sum the amounts of each remittance and add it back as total amount in JavaScript. I understand the logic of what needs to occur, I am just unsure of the proper syntax.
I'm struggling because of the way the data is nested and the varied number of amounts uder each remittance.
I would appreciate any insite.
this is an example of what I would need for my final result--
{
"payment": {
"vendor": {
"name": "Amazon Web Service, Inc.",
"address": "410 Terry Avenue North",
"address2": "",
"city": "Seattle",
"state": "WA",
"zip": "98109-5210",
"industry": "Computer Integrated Systems Design"
},
"remittance": [{
"invoice_number": "inv# 509193",
"invoice_date": "2020-09-07",
"description": "premium support",
"amount": 4000
},
{
"invoice_number": "inv# 939032",
"invoice_date": "2020-09-10",
"description": "hosting fees",
"amount": 6000
}
],
"total_amount": 10000
}
}
Below is the data I am trying to analyze.

You should be able to do this with built in array functions:

const result = data.reduce((sum, item) => {
const remittance = Array.isArray(item.payment.remittance) ? item.payment.remittance : [item.payment.remittance];
const remittanceAmount = remittance.reduce((total, remit) => {
total = total remit.amount;
return total;
}, 0);
return sum remittanceAmount;
}, 0);
console.log(result)Notice you need a inner reduce in the case there are multiple remittances.
CodePudding user response：
try this
data.forEach((item) => {
var result = 0;
if (item.payment.remittance.amount == undefined)
result = item.payment.remittance.reduce(function (rem, obj) {
return rem obj.amount;
}, 0);
else result = item.payment.remittance.amount;
item.payment.total_amount = result;
});
and you have an invalid place in your json, instead of "remittance": [, it is "remittance": { . I included a work around in my code, but IMHO it needs to be fixed some way. I think it is easier to fix api that produces json.
