Sorted Objected based on nested object value

Question

I have an object that I would like to sort based on the votes that it has, and then map over the new / sorted object.

const data = {
  "comment-1508872637211" : {
    "description" : "Blah",
    "votes" : 1
  },
  "comment-1508872675949" : {
    "description" : "Question",
    "votes" : 11
  },
  "comment-1508898578089" : {
    "description" : "whatever\n",
    "votes" : 5
  },
  "comment-1508898637092" : {
    "description" : "new",
    "votes" : 15
  },
  "comment-1508900306998" : {
    "description" : "baj",
    "votes" : 0
  }
}

console.log(data);

const sortedOnVotes = Object.entries(data);

console.log(sortedOnVotes);

// This is the part I'm getting hung up on
const newDataObject = sortedOnVotes.map(([key, value]) => value).sort();

console.log(newDataObject)

Ultimately I would love for this new object to still retain the comment-### key and be filtered based on the amount of votes that it has. For example the newDataObject should return something like this:

const newDataObject = {
          "comment-1508900306998" : {
            "description" : "baj",
            "votes" : 0
          },
          "comment-1508872637211" : {
            "description" : "Blah",
            "votes" : 1
          },
          "comment-1508898578089" : {
            "description" : "whatever\n",
            "votes" : 5
          },
          "comment-1508872675949" : {
            "description" : "Question",
            "votes" : 11
          }
          "comment-1508898637092" : {
            "description" : "new",
            "votes" : 15
          }

}

I think I'm on the right track by using Object.values or Object.entries but I'm really getting hung up on it.

Any help would really be appreciated, thanks!

javascript object can be sorted, move them to array if you need to sort — brk

Use lodash/sort, easy to use and simple to configure. See lodash here. — Umesh

You can write the logic to sort the arrays using the sort() function like below-

const data = {
  "comment-1508872637211" : {
    "description" : "Blah",
    "votes" : 1
  },
  "comment-1508872675949" : {
    "description" : "Question",
    "votes" : 11
  },
  "comment-1508898578089" : {
    "description" : "whatever\n",
    "votes" : 5
  },
  "comment-1508898637092" : {
    "description" : "new",
    "votes" : 15
  },
  "comment-1508900306998" : {
    "description" : "baj",
    "votes" : 0
  }
}

console.log(data);

const sortedOnVotes = Object.entries(data);

console.log(sortedOnVotes);

var result = sortedOnVotes.sort(function(a,b) {
  return a[1].votes - b[1].votes;
});

console.log(result);

Thanks, looks like this is getting it sorted for me. Im still curious if I could get it back into the same format as it was originally as an object with a key and an object value pair. With your answer it's an array of array.
