Compare JSON object array using Jquery

I have a selected list object like this {"0":"1","2":"1"}, I want to compare it with another array like the following

{
  "0": {
    "id": 1,
    "salutation": "Dr.",
    "firstname": "Kapil",
    "lastname": "Dev",
    "gender": "Male ",
    "email": "[email protected]",
    "phone": 1232423415,
    "usertype": "student",
    "institution": "AgriGenome Labs Pvt Ltd",
    "department": "Lab",
    "country": "India",
    "conferenceitem": "2017 NGBT Conference ",
    "conferenceitemid": "39",
    "amount": 2800,
    "actual_amount": "5000.00",
    "currency": "INR",
    "group": "Lead",
    "accompany": "No",
    "password": null,
    "mailsend": "Yes"
  },
  "1": {
    "id": 2,
    "salutation": "Mr.",
    "firstname": "Sunil",
    "lastname": "Gavaskar",
    "gender": "Male ",
    "email": "[email protected]",
    "phone": 1232423415,
    "usertype": "commercial",
    "institution": "AgriGenome Labs Pvt Ltd",
    "department": "Bio Info",
    "country": "India",
    "conferenceitem": "2017 NGBT Conference ",
    "conferenceitemid": "31",
    "amount": "3100.00",
    "actual_amount": "10000.00",
    "currency": "INR",
    "group": "Yes",
    "accompany": "No",
    "password": null,
    "mailsend": "Yes"
  },
  "2": {
    "id": 3,
    "salutation": "Mr.",
    "firstname": "Anil",
    "lastname": "Kumble",
    "gender": "Male ",
    "email": "[email protected]",
    "phone": 1232423415,
    "usertype": "student",
    "institution": "AgriGenome Labs Pvt Ltd",
    "department": "Support",
    "country": "India",
    "conferenceitem": "Accompanying Person",
    "conferenceitemid": "5",
    "amount": 1900,
    "actual_amount": "5000.00",
    "currency": "INR",
    "group": "No",
    "accompany": "Yes",
    "password": null,
    "mailsend": "No"
  }
}

on the basis of the keys, means that only 0 & 2 are selected and I need to fetch data from the second object having key 0 & 2, (excluding 1 ), how can I do this? I am new to this area...

Considering you only want to the object filtered out from your selection, you could use forEach on Object.keys of your selected object

var obj = {"0":"1","2":"1"};
var newobj = {
  "0": {
    "id": 1,
    "salutation": "Dr.",
    "firstname": "Kapil",
    "lastname": "Dev",
    "gender": "Male ",
    "email": "[email protected]",
    "phone": 1232423415,
    "usertype": "student",
    "institution": "AgriGenome Labs Pvt Ltd",
    "department": "Lab",
    "country": "India",
    "conferenceitem": "2017 NGBT Conference ",
    "conferenceitemid": "39",
    "amount": 2800,
    "actual_amount": "5000.00",
    "currency": "INR",
    "group": "Lead",
    "accompany": "No",
    "password": null,
    "mailsend": "Yes"
  },
  "1": {
    "id": 2,
    "salutation": "Mr.",
    "firstname": "Sunil",
    "lastname": "Gavaskar",
    "gender": "Male ",
    "email": "[email protected]",
    "phone": 1232423415,
    "usertype": "commercial",
    "institution": "AgriGenome Labs Pvt Ltd",
    "department": "Bio Info",
    "country": "India",
    "conferenceitem": "2017 NGBT Conference ",

    "currency": "INR",
    "group": "Yes",
    "accompany": "No",
    "password": null,
    "mailsend": "Yes"
  },
  "2": {
    "id": 3,
    "salutation": "Mr.",
    "firstname": "Anil",
    "lastname": "Kumble",
    "gender": "Male ",

  }
}

const result = {}
Object.keys(obj).forEach(key => {
    result[key] = newobj[key]
})
console.log(result)
