I am working on javascript object. And I want to pass data to next array in a specific sequence. like I get data like this

var obj = [{
  0: "Owner Name"
  1: "Mailing Address"
  2: "Situs Address"
  3: "APN"  
}]

And want this sequence to be like this

var obj = [{
  3: "APN"  
  0: "Owner Name"
  2: "Situs Address"  
  1: "Mailing Address" 
}];

Is it possible to do that, on bases of data? As I don't know from database sequence maybe change. edit: For those who are saying I should use array. I am getting data on basis of this object like,

 var data[{
  0:"CHANCE WILLIAM C & KATHRYN L"
  1:"P O BOX 7642 CHICO CA 95927"
  2:"LOT 4 PM 150-99/100"
  3:"040-310-086-000" }]

• 2 The properties in an object are not, and can not be, ordered in any way, so what you're trying to do is not possible. If you want to have a guaranteed order to the values put them in an array instead – Rory McCrossan Commented Jul 7, 2017 at 7:38
• The only way is to build another Map object by specifying keys & values in your desired order. But, why do you want to do this? Ordering of keys doesn't affect how you access the values.. – Chris Lam Commented Jul 7, 2017 at 7:39

Object not have sorting property

so you can do like this,

Covert the array object arguments into individual object.then sorting with dec order of the key

var obj = [{
  '0': "Owner Name",
  '1': "Mailing Address",
  '2': "Situs Address",
  '3': "APN" ,
}];

var array = Object.keys(obj[0]).map(function(a){
                  return ({[a]:obj[0][a]});
}) //recreate with individual object

var sorted= array.sort((a,b)=> Object.keys(b)-Object.keys(a))
 console.log(sorted) //sorted  object
 
var res = sorted.map(a=> Object.values(a)[0]) // for array

console.log(res)

The properties in an object are not, and can not be, ordered in any way, so what you're trying to do is not possible. If you want to have a guaranteed order to the values put them in an array instead.

For those who are saying I should use array. I am getting data on basis of this object

In this case you can use Object.keys() and map() to convert the object to an array:

var data = [{
  0: "CHANCE WILLIAM C & KATHRYN L",
  1: "P O BOX 7642 CHICO CA 95927",
  2: "LOT 4 PM 150-99/100",
  3: "040-310-086-000"
}];

var arr = Object.keys(data[0]).map(function(k) {
  return data[0][k];
});
console.log(arr);

The keys in a JavaScript object do not have any order. They will be displayed in any order and can change because order is not preserved.

If you need your data in a particular order, use an Array.

Example of an array of strings preserving order

var orderedItems = [
  "3: APN",
  "0: Owner Name",
  "2: Situs Address",
  "1: Mailing Address"
];
