react native creating object with arrays

i have arrays like this:

[
0: {barcode: '4124121241241', qty: 1}
1: {barcode: '1234124135134', qty: 1}
2: {barcode: '3573424625234', qty: 1}
3: {barcode: '2346468457354', qty: 1}
4: {barcode: '5684452043432', qty: 1}
5: {barcode: '1241263475686', qty: 5}
6: {barcode: '1231241231423', qty: 15}
]

and i’m pushing those like this:

shelfArray.push({
    [rafName]:JSON.parse(results.rows.item(index).BarcodeArray)
});

this is my output:

0:
Q1:
BarcodeArray: [{…}]
1:
Q2:
BarcodeArray: (7) [{…}, {…}, {…}, {…}, {…}, {…}, {…}]
2: {Q3: null}

but i want this like :

Q1:
BarcodeArray: [{…}]
Q2:
BarcodeArray: (7) [{…}, {…}, {…}, {…}, {…}, {…}, {…}]
2: {Q3: null}

how can do that ?

>Solution :

Rather than creating shelfArray as an array [], create it as an empty object

const shelfArray = {}; // rather than `= [];`

and then add keys to that object as you loop instead of
pushing by using bracket notation:

shelfArray[rafName] = JSON.parse(results.rows.item(index).BarcodeArray);
