Answer 1

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)
