Postman - Looping through an array of nested objects to make a variable

I am trying to set a variable from following phone number with value: “+33652556777” (index 4 in JSON attached below) which is the last object in contacts (index 4).
To do so is pretty simple:
let jsonData = pm.response.json();
console.log (jsonData.contacts[4].phone_numbers[0].value)
const PhoneNumber = jsonData.contacts[4].phone_numbers[0].value
pm.environment.set("Jacky", PhoneNumber);
Since I have to use different query parameters to filter by eg. created_at=asc, desc, the property of the phone_numbers order might change index number and I won’t be able to fetch desire phone number "+33652556777” instead it will set a different phone number which I cannot allow.
I know there is way to fetch our number and make it variable for next requests, which is iterating over properties or keys in the object “ for….in or for…of ” but for some reason I cannot achieve it.
What I could achieve is to get through first object “contacts” but impossible to get to its nested array “phone_numbers”. Here is how I did it:
let jsonData = pm.response.json();
let contact;
for (let filter of jsonData.contacts){
if (filter.last_name == "Rowland"){
contact = filter;
}}
console.log (contact);
Could you please help?

You could use something basic like this:
_.each(pm.response.json().contacts, (contact) => {
if(contact.last_name === "Rowland") {
pm.environment.set(`${contact.first_name}_${contact.last_name}_number`, contact.phone_numbers[0].value)
}
})
There are probably better and more performant ways to do this but if you just want to set a variable for that contact, no matter where they are in the response - This would work :D

you can use forEach or _.each as danny mentioned to get all numbers else use:
console.info(jsonData.contacts.find((a)=>a.first_name==="Jacky").phone_numbers[0].value)
use array.find to find the contact with first_name jacky adn then get phone_number[0].value from it.
if you want all numbers from that array then use:
console.info(jsonData.contacts.find((a)=>a.first_name==="Jacky").phone_numbers.map((a)=>a.value))
here we map the result to get only the numbers from phone_number array.
is it what you looking for !?

Restructuring JSON before input

Here's an example of object from the JSON output of my database:
{
"id": "http://...",
"type": "example-type",
"title": "Example title",
"container-title": "Example container title",
"page": "1-100",
"issue": "3",
"URL": "http://www.url",
"ISSN": "0123-0123",
"author": [
{
"family": "Smith",
"given": "John"
}
],
"issued": {
"date-parts": [
[
"2000"
]
]
},
"keyword": "Sample Tag"
}
I've had enormous difficulties/bugs referring to the nested fields for author and date when building a data table. What I would like to do is somehow modify/flatten this before using it in the table (using Datatables' dataSrc as described here) and then simply call the restructured data as many times as I need using the datatables API.
So what I now refer to as issued.date-parts.0.0 would be simply year. The structure would be instead:
"authors": "John Smith", "Mark Smith"
"year": "2000"

Use the map function to get the authors
Look at this code snippet
var data = { "id": "http://...", "type": "example-type", "title": "Example title", "container-title": "Example container title", "page": "1-100", "issue": "3", "URL": "http://www.url", "ISSN": "0123-0123", "author": [ { "family": "Smith", "given": "John" }, { "family": "Smith", "given": "Mark" } ], "issued": { "date-parts": [ [ "2000" ] ] }, "keyword": "Sample Tag"};
var result = {
"authors": data.author.map((d) => `${d.given} ${d.family}`),
"year": data.issued['date-parts'][0][0]
}
console.log(result);
.as-console-wrapper {
max-height: 100% !important
}

JSON.PARSE without loosing header array field

function main(message){
...
phone= JSON.parse(message.phoneNumbers);
... }
My input JSON is
{
"firstName": "John",
"lastName": "Smith",
"isAlive": true,
"age": 25,
"address": {
"streetAddress": "21 2nd Street",
"city": "New York",
"state": "NY",
"postalCode": "10021-3100"
},
"phoneNumbers": [
{
"type": "home",
"number": "212 555-1234"
},
{
"type": "office",
"number": "646 555-4567"
},
{
"type": "mobile",
"number": "123 456-7890"
}
],
"children": [],
"spouse": null
}
The result I receive is omitting the "phoneNumbers" but I do want it.

Your data is correct, when i JSON.parse it, i get everything allright.
But you don't seem to access to your data in the right way. You must first parse the whole JSON, then you have a javascript object, and only then you can acces your property.
in detail:
var obj = JSON.parse(message);
var phone = obj.phoneNumbers;
or in short:
var phone = (JSON.parse(message)).phoneNumbers;

How to Accessing fields from custom search results in netsuite?

In the ui, I have created a custom transaction search with vendor lines. How do I access vendor lines values? I have something like this:
var veResults = vendorSearch.run().getRange({
start: 0,
end: 50
});
for(var i = 0; i < veResults.length; i++)
{
var vendorName = veResults[i].getValue({name: 'vendorLine.entityid');
context.response.write(vendorName);
};
If I print veResults, I get the following json:
[
{
"recordType": "vendorpayment",
"id": "210",
"values": {
"employee.entityid": "",
"trandate": "5/20/2015",
"print": "Print",
"type": [
{
"value": "VendPymt",
"text": "Bill Payment"
}
],
"payrollbatch": "",
"tranid": "2009",
"entity": [
{
"value": "35",
"text": "Pacific Bell Telephone"
}
],
"account": [
{
"value": "1",
"text": "1000 Checking"
}
],
"otherrefnum": "",
"statusref": [],
"trackingnumbers": "",
"memo": "",
"currency": [
{
"value": "1",
"text": "USA"
}
],
"expectedreceiptdate": "",
"trandate_1": "5/20/2015",
"enddate": "",
"item": [],
"vendorLine.entityid": "Pacific Bell Telephone",
"vendorLine.billaddress": "Pacific Bell Telephone\nPacific Bell Payment Center\nSacramento CA 95887-0001\nUS"
}
...]
So, the value is there, how do I get it? The search object has only getValue and getText methods, none of which work in this case.

There is a syntax error with this line
var vendorName = veResults[i].getValue({'vendorLine.entityid');
It should be
var vendorName = veResults[i].getValue('vendorLine.entityid');

Group and limit for multiple groups

I have the following documents
{
"_id": "id",
"_rev": "123456",
"author": "john",
"views": "3",
},
{
"_id": "id",
"_rev": "123456",
"author": "jake",
"views": "5",
},
{
"_id": "id",
"_rev": "123456",
"author": "jake",
"views": "6",
},
{
"_id": "id",
"_rev": "123456",
"author": "john",
"views": "1",
},
{
"_id": "id",
"_rev": "123456",
"author": "jake",
"views": "7",
},
{
"_id": "id",
"_rev": "123456",
"author": "john",
"views": "10",
}
Lets suppose that these are comments and I would like to get the 2 most viewed comments by user.
How can I do that in CouchDB?
In any other sql database I could perform 2 queries with limit 2 and then merge the results.

If you have an array with that data in JavaScript you can simply use the sort method:
var a = [{...}, {...}, {...}];
a.sort(function(a, b) {
return b.views - a.views;
});
console.log(a[0]) //{ "_id": "id", "_rev": "123456", "author": "john", "views": "10" }
console.log(a[1]) //{ "_id": "id", "_rev": "123456", "author": "jake", "views": "7" }
If you want to only have the to most viewed records you can use the slice method
var a = [...];
a.sort(...);
a = a.slice(0, 2);

I guess you could just use this map:
function (doc) {
emit([doc.author, -doc.views], null);
}
without the reduce. Query with options ?startkey=['john']&limit=2 should result with something like:
{"total_rows":5,"offset":0,"rows":[
{"id":"id1","key":["john",-10],"value":null},
{"id":"id2","key":["john",-3],"value":null}
]}
Note the - sign when emitting doc.view to get biggest view count. You can also use descending=true option, but it will also reverse the order of the author string. This is not natural order for strings and you might need that in the future ;)
