I have array of objects data, in each object i have nested array, in that array i need to remove the object if element has a array.
Input Data :-
const data = [{"userDetails":[{"username":"Sai ","profileUrl":"","_id":4},{"username":"Mohamed Abu","profileUrl":"","_id":1},4,1]},{"userDetails":[{"username":"Sai ","profileUrl":"","_id":4},{"username":"Mohamed Abu","profileUrl":"","_id":1},4,1]},{"userDetails":[{"username":"Sai ","profileUrl":"","_id":4},4]},{"userDetails":[{"username":"Mohamed Abu","profileUrl":"","_id":1},1]}]
Expected Output Data : -
data = [
{
userDetails: [4, 1],
},
{
userDetails: [4, 1],
},
{
userDetails: [4]
},
{
userDetails: [1]
},
];
Please help me in these issue.
Thanks in advance.
The following snippet should do the job.
data.map(x => removeNestedObj(x))
function removeNestedObj(x)
{
x.userDetails = x.userDetails.filter(y => Number.isInteger(y))
return x;
}
const data = [{"userDetails":[{"username":"Sai ","profileUrl":"","_id":4},{"username":"Mohamed Abu","profileUrl":"","_id":1},4,1]},{"userDetails":[{"username":"Sai ","profileUrl":"","_id":4},{"username":"Mohamed Abu","profileUrl":"","_id":1},4,1]},{"userDetails":[{"username":"Sai ","profileUrl":"","_id":4},4]},{"userDetails":[{"username":"Mohamed Abu","profileUrl":"","_id":1},1]}];
let finalData = data.map(a => a.userDetails) //get userDetails array
.map(a => a.filter(x => typeof x !== 'object')) //remove objects from array
.map(a => {
return {userDetails: a} //recreate object with key userDetails
});
console.log(finalData);You can use map and filter and compare with typeof same as :
const data = [{
"userDetails": [{
"username": "Sai ",
"profileUrl": "",
"_id": 4
}, {
"username": "Mohamed Abu",
"profileUrl": "",
"_id": 1
}, 4, 1]
}, {
"userDetails": [{
"username": "Sai ",
"profileUrl": "",
"_id": 4
}, {
"username": "Mohamed Abu",
"profileUrl": "",
"_id": 1
}, 4, 1]
}, {
"userDetails": [{
"username": "Sai ",
"profileUrl": "",
"_id": 4
}, 4]
}, {
"userDetails": [{
"username": "Mohamed Abu",
"profileUrl": "",
"_id": 1
}, 1]
}]
// for removing object in userDetails
const result = data.map(obj => ({userDetails: obj.userDetails.filter(e => typeof e !== 'object')}))
console.log(result)
// for getting numbers in userDetails
const result1 = data.map(obj => ({userDetails: obj.userDetails.filter(e => typeof e === 'number')}))
console.log(result1)
