@hindmost i know its object literal, how can i sort the data on the basis of 'id' — shairoo, Dec 12 '18 at 06:53
an objects order cannot be garunteed, so how do you want this to be sorted? — Nick Parsons, Dec 12 '18 at 07:03

First of all, you shouldn't rely on property order in JavaScript objects (see this question for details), which means that you need to sort your objects into an array.

That can easily be done using Array.prototype.sort():

const sorted = Object.values(data).sort((a, b) => a.id - b.id);

Complete snippet:

const data = {
  1918: {
    id: "1544596802835",
    item_id: "1918",
    label: "Soft Touch  Salt Free Mint 500 ml (000001400045)",
    combo_items: false
  },
  6325: {
    id: "15445968134652",
    item_id: "6325",
    label: "Mirindas Orange Flover 300 ml (012000800160)",
    combo_items: false
  },
  6336: {
    id: "15445968106815",
    item_id: "6336",
    label: "Sting Energy 250ml (012000034220)",
    combo_items: false
  },
  6498: {
    id: "1544596806967",
    item_id: "6498",
    label: "Tido Candy (01)",
    combo_items: false
  },
  7461: {
    id: "15445968057103",
    item_id: "7461",
    label: "Skin Whitening Facial Kit (000051032012)",
    combo_items: false
  }
};

const sorted = Object.values(data).sort((a, b) => a.id - b.id);

console.log(sorted);

^{(I fixed the object literal as it was lacking commas between the properties)}

You can try!

function sort(data) 
{
   return Object.keys(data)
   .sort().reduce((a, b) => {
   a[b] = data[b];
   return a; }, {});
}

const object = {9:"Name 9", 10:"Name 10", 2:"Name 2", 5:"Name 5", 3:"Name 3"};
var sortObject = sort(abject);

The result is

sortObject = {2: "Name 2", 3: "Name 3", 5: "Name 5", 9: "Name 9", 10: "Name 10"}
