Issue
I am trying to change the value of object from the array but, it’s not work as expected. I tried following.
const arrObj = [
{
"label": "test1",
"value": 123,
"type": "number",
"field": {
"label": "another",
"description": "abcd"
}
},
{
"label": "test2",
"value": 111,
"type": "number"
},
]
arrObj.forEach(obj => {
obj = {...obj, ...obj.field}
delete obj.field
})
console.log("after:", arrObj);Also I found some solution that to use index but, it add index before the object.
const arrObj = [
{
"label": "test1",
"value": 123,
"type": "number",
"field": {
"label": "abcd",
"description": "abcd"
}
},
{
"label": "test2",
"value": 111,
"type": "number"
}
]
arrObj.forEach((obj, index) => {
obj[index] = {...obj, ...obj.field}
delete obj.field
})
console.log("after:", arrObj);How can I do with forEach?
Edit:
I want to remove the field object and assign/overwrite all the property outside.
Solution
Using map and assigning the result is probably a better way of doing this, but if you want to use forEach, you need to assign to the original array inside the loop:
const arrObj = [
{
"label": "test1",
"value": 123,
"type": "number",
"field": {
"label": "another",
"description": "abcd"
}
},
{
"label": "test2",
"value": 111,
"type": "number"
},
]
arrObj.forEach(({ field, ...rest}, idx, orig) => {
orig[idx] = { ...rest, ...field }
})
console.log(arrObj);Answered By – Nick
