Q:

How to Sort object arrays by its key value

I have Object with arrays like below , I am trying to sort it ascending and descending by its value (rank) 
AXISBANK: [rank: 110, bnrank: 110, bs: 75, ss: 3]
BANKBARODA: [rank: 32, bnrank: 5, bs: 83, ss: 26]
HDFCBANK: [rank: 453, bnrank: 453, bs: 52, ss: 33]

So output array is like below if descending .. and reverse for ascending
HDFCBANK: [rank: 453, bnrank: 453, bs: 52, ss: 33]
AXISBANK: [rank: 110, bnrank: 110, bs: 75, ss: 3]
BANKBARODA: [rank: 32, bnrank: 5, bs: 83, ss: 26]

I tried following code
scorearr.sort((obj1, obj2) => obj1.bnrank - obj2.bnrank);
And also below code
function compares(a,b) {
console.log(a.bnrank);
  if (a.bnrank < b.bnrank)
    return -1;
  if (a.bnrank > b.bnrank)
    return 1;
  return 0;
}
scorearr.sort(compares);

Still scorearr is unchanged and its in old order only.
Edit : Below is sample data
{
  "HDFCBANK": {
    "rank": 453,
    "bnrank": 453,
    "bs": 52,
    "ss": 33
  },
  "ICICIBANK": {
    "rank": 228,
    "bnrank": 228,
    "bs": 88,
    "ss": 3
  },
  "KOTAKBANK": {
    "rank": 164,
    "bnrank": 164,
    "bs": 23,
    "ss": 82
  }
}

This is how I am creating this object ,please tell me if any alternative if this thing can be done easily.
var scorearr = {};
//loop here
var id = $(this).attr('id');
scorearr[id] = {};
scorearr[id] = {rank:nfscore,bnrank:bnscore,bs:sellscore,ss:buyscore};
//end loop

A:

If you have an object with nested objects, you could take the entries (key/value pairs), sort this array and rebuild a new object with the sorted order.

var data = { AXISBANK: { rank: 110, bnrank: 110, bs: 75, ss: 3 }, BANKBARODA: { rank: 32, bnrank: 5, bs: 83, ss: 26 }, HDFCBANK: { rank: 453, bnrank: 453, bs: 52, ss: 33 } },
    sorted = Object.assign(...Object
        .entries(data)
        .sort(({ 1: { bnrank: a } }, { 1: { bnrank: b } }) => b - a)
        .map(([k, v]) => ({ [k]: v }))
    );

console.log(sorted);
.as-console-wrapper { max-height: 100% !important; top: 0; }

Another approach with an array.

var data = [{ id: 'AXISBANK', rank: 110, bnrank: 110, bs: 75, ss: 3 }, { id: 'BANKBARODA', rank: 32, bnrank: 5, bs: 83, ss: 26 }, { id: 'HDFCBANK', rank: 453, bnrank: 453, bs: 52, ss: 33 }];


data.sort(({ bnrank: a }, { bnrank: b }) => b - a);

console.log(data);
.as-console-wrapper { max-height: 100% !important; top: 0; }
