Array of Object Manipulation

Dashboard
1

Hello,

i would like to take Values of Objects in an array (orr), manipulate them and put them with new added Values in a new array(urr) of Objects.

The Code:

let orr = []
let urr = []
let uobj
let obj
var k = 10 
orr = global.get('grml')

for(let i=0;i<k;i++){
    uobj = {}
    obj = {}
    obj.Barcode1 = "A"
    obj.Barcode2 = "B"
    obj.Barcode3 = "C"
    uobj.Barcode4 = obj.Barcode4 
    obj.Quark = "does not taste good"
    obj.NeuerQuark = "Vorhanden"
    uobj.NeueStelle = i
    urr.push(uobj)
}   
const komps = urr;
node.warn(k)
msg.payload = komps
return msg;

I get the new Array of Objects but only with the Value of "NeueStelle".
How do i get Values from Array of Object A to Values in Array of Objects B ?

Greetings

What is your input array and the expected output?

3

urr is my output array, orr is the array with the original data.

originalarrayofobjects

i want to add/change values on the original array.
Changing the Value of Barcode1...4 or add a new one.
i am working on other solutions atm, but nothing works for me ...

when supplying input data it is best to give an example that can be copied and pasted. Then people helping you can then run it against your code to see the issue. There is no need to supply the full data just enogh to use as an example.

The Testflow:
change Array of objects

The Code:

may be that helps, its a test flow for getting a solution

I found a working solution!
