How to make a Leaderboard using objects inside objects? Javascript

Question

so I am trying to make a leaderboard of the players with more points, the object kinda looks like this:

let currency = {
    person1: {
        money: 1004,
        level: 20
    },
    person2: {
        money: 124,
        level: 3
    },
    person3: {
        money: 50144,
        level: 102
    }
}

and what I want to do is it to create a leaderboard based on everyone's MONEY (not level) For example:

person3 | 50144
person1 | 1004
person2 | 124

Any help will be appreciated since i have been stuck in this part.

Too bad it's not an array of objects, then it'd be a trivial property-based sort. (That's a hint :) — Dave Newton, Jun 23 '21 at 13:56

Try iterating over your object using Object.entries, then you can filter the output array with Array.sort() and finally just Array.map() in order to get your desired format.

const currency = {
  person1: {
    money: 1004,
    level: 20,
  },
  person2: {
    money: 124,
    level: 3,
  },
  person3: {
    money: 50144,
    level: 102,
  },
};

const result = Object.entries(currency)
  .sort((a, b) => b[1].money - a[1].money)
  .map((p) => `${p[0]} | ${p[1].money}`);

console.log(result);
