How do I only send the top 3 values of my JSON file?

xp.json

{
  "405778045941841923":{"xp":12601,"level":43},
  "437502925019807744":{"xp":221,"level":1},
  "258877808489660416":{"xp":6623,"level":23}, ...
}

index.js

if (cmd === `${prefix}list`) {
    console.log(Object.keys(xpfile).reduce((list, username) => {
        list += `${username}: XP: ${xp[username].xp}\n`
        return list
    }, ''))
}

output:

405778045941841923: XP: 12601
437502925019807744: XP: 221
258877808489660416: XP: 6623
381904022132752384: XP: 81

I would appreciate any code example since I am having a hard time calling JSON objects in code, I basically only want to show the top 3 highest XP

I'd sort, slice and reduce

let j = {"405778045941841923":{"xp":12601,"level":43},"437502925019807744":{"xp":221,"level":1},"258877808489660416":{"xp":6623,"level":23}};
let top3 = Object.keys(j).sort((a, b) => j[b].xp - j[a].xp).slice(0, 3).reduce((a, b) => {
  a[b] = j[b];
  return a;
}, {});
console.log(top3);
