Postman - taking attributes and values from one JSON to create another JSON - postman

Question

This in relation to my older ticket here!
But now I need to get more advanced. I need to get only certain attributes and their values (from the 1st Response JSON) to create another JSON (and some values to be replaced in new JSON).
I.e. in the Response JSON below, I need to go through all "Items" (and I do not know in advance how many those can be), and get only Id + value, and Status+value for each of them. Then to build another new JSON, where the top attribute will be called Products instead of Variations, and contain only Id+value and Status+*NewValue*.
1st Response JSON:
"Variations":[
{
"ItemIds":[
"xxx"
],
"Items":[
{
"Id":"67-V1",
"GuId":"xxx",
"Type":"Unit",
"Status":"Active"
}
],
"Name":"VAR 1",
"Id":"67-V1"
},
{
"ItemIds":[
"yyy"
],
"Items":[
{
"Id":"67-V2",
"GuId":"yyy",
"Type":"Unit",
"Status":"Active"
}
],
"Name":"VAR 2",
"Id":"67-V2"
},
{
"ItemIds":[
"zzz"
],
"Items":[
{
"Id":"67-V3",
"GuId":"zzz",
"Type":"Unit",
"Status":"Active"
}
],
"Name":"VAR 3",
"Id":"67-V3"
}
],
"ItemIds":[
],
"Items":[
],
"Name":"MAINP",
"Id":"67",
"Color":null
}
New JSON I would like to create:
{
"Products":[
{
"Id":"67-V1",
"Status":"NonActive"
},
{
"Id":"67-V2",
"Status":"NonActive"
},
{
"Id":"67-V3",
"Status":"NonActive"
}
]
}
I have made following code:
var jsonData = pm.response.json();
var newData;
var newDataGroup = "";
function replaceValues() {
_.each(jsonData.Variations, (arrayItem) => {
_.each(arrayItem.Items, (item) => {
if(item.Status !== "NonActive") {
item.Status = "NonActive";
console.log("arrayItem " + item.Status);
}
newData = "{ \"Id\":\"" + item.Id + "\", " + " \"Status\":\"" + item.Status + "\"},";
newDataGroup = newDataGroup + newData;
});
});
newDataGroup = "{ \"Products\": [ " + newDataGroup + " ] }";
}
pm.test("Run Replace", replaceValues ());
console.log("newDataGroup Final: " + newDataGroup);
var newJson = JSON.parse(newDataGroup);
console.log("newJson: " + newJson);
Here is my outcome (based on the code above), but how to deal with the last , there?
{
"Products":[
{
"Id":"67-V1",
"Status":"NonActive"
},
{
"Id":"67-V2",
"Status":"NonActive"
},
{
"Id":"67-V3",
"Status":"NonActive"
},
]
}

Seems like here is the final code that will do the trick. While most likely, not the most elegant but does the job. If anyone can suggest the more elegant way, would be appreciated.
var jsonData = pm.response.json();
var newData;
var newDataGroup = "";
function replaceValues() {
_.each(jsonData.Variations, (arrayItem) => {
_.each(arrayItem.Items, (item) => {
if(item.Status !== "NonActive") {
item.Status = "NonActive";
}
newData = "{ \"Id\":\"" + item.Id + "\", " + " \"Status\":\"" + item.Status + "\"},";
newDataGroup = newDataGroup + newData;
});
});
newDataGroup = newDataGroup.slice(0, -1);
newDataGroup = "{ \"Products\": [ " + newDataGroup + " ] }";
}
pm.test("Run Replace", replaceValues ());
var newJson = JSON.parse(newDataGroup);
