Best way to format the JSON content in Node.js application - node.js

Question

I am working on an NODE JS based application. Trying to figure out any easy method to get my expected result. Had tried few ways, but after reframing the JSON content not able to add the key state.
My content JSON content is in this format
[
{
"item": {
"property1": "aa",
"property2": "22"
},
"state": {
"item": {
"state": "AS",
"country": "US",
"reason": "1"
}
},
"province": {
"item": {
"name": "AS",
"method": "table",
"conf": "3"
}
}
},
...
]
Requirement is to format state as below,
{
...
"state": [
{
"item": {
"state": "AS",
"country": "US",
"reason": "1"
}
}
],
...
}
I want to format the state content. The content is expected to be an array of JSON content. After formatting state, the orginal json content need to be modified with the new content of state. The issue faced here is after formatting not able to add the key state back to the orginal JSON content.Same is the expectation for province.
Requesting support from All...Thanks in Advance....
Below is the code i had written, but the expected result is not obtained.Can anyone help me in identifying were i have gone wrong
var testJson = JSON.parse(jsonData);
var tempFinal = [];
for(let i =0; i<testJson.length; i++) {
let itemData = {};
itemData.item = testJson[i].item;
tempFinal.push(itemData);
var state = [];
state.push( testJson[i].state);
let stateData = {};
stateData.state = state;
tempFinal.push(stateData);
var service = [];
service.push( testJson[i].service);
let serviceData = {};
serviceData.service = service;
tempFinal.push(serviceData);
}
The result obtained is
[
{
"item": {
"protocol": "tcp",
"portid": "22"
}
},
{
"state": [
{
"item": {
"state": "filtered",
"reason": "no-response",
"reason_ttl": "0"
}
}
]
},
{
"service": [
{
"item": {
"name": "ssh",
"method": "table",
"conf": "3"
}
}
]
}
]
Expected is
[
{
"item": {
"a": "a",
"a": "a"
},
"state": [
{
"item": {
"c": "b",
"e": "f",
"reason_ttl": "0"
}
}
],
"service": [
{
"item": {
"name": "q",
"method": "table",
"d": "e"
}
}
]
}
]

You can try this one
//jsonData is your original json data
jsonData.map((obj1=>{
//updating state data
obj1.state=[obj1.state];
}));
//finally print it.
console.log(jsonData);
