Create an array of object like this:
var nietos = [];
nietos.push({"01": nieto.label, "02": nieto.value});
return nietos;
First you create the object inside of the push method and then return the newly created array.

Push is an array method but your trying to add data to an object so that isnt going to work. To add data to an obect you need to either: obj.key = ['array'] obj['key'] = ['array'] If an object key is already an array you can: obj.key.push('something) edit: realised it is an array, so the above follows but you want: array[index].key = ['item'] array[index][key] = ['item'], or if already an array array[index][key].push('item) More on reddit.com

Object is a reference type, so you can get the target object from the array by index and then update its newArr property.
let arr = [{
name: {
"id": 1
},
data: {
"dataVal": 'value1'
}
}, {
name: {
"id": 2
},
data: {
"dataVal": 'value2'
}
}, {
name: {
"id": 3
},
data: {
"dataVal": 'value3'
}
}]
const update = (array, index, property, value) => {
array[index][property] = value;
}
update(arr, 0, "newArr", [])
console.log(arr); 2 of 4

Try this simple utility function.
const newArr = [1, 2, 3]
const arr = [{
name: {
"id": 1
},
data: {
"dataVal": "value1"
}
}, {
name: {
"id": 2
},
data: {
"dataVal": "value2"
}
},
{
name: {
"id": 3
},
data: {
"dataVal": "value3"
}
}
]
function insertArr(ar, i, newAr) {
ar[i] = { ...ar[i],
newAr
}
return ar
}
console.log(insertArr(arr, 1, newArr)) Top answer 1 of 3
