This gist returns objects in an array in order of their ranks, and also returns the average rank for each of object in an array

objectRanker.js

const testArr = [
  {
  name: 'Ade',
  ranking: 1
  },
  {
  name: 'Luqman',
  ranking: 2
  }
];

const objectRanker = (arrs) => {
  return arrs.sort((a, b) => {
      return b.ranking - a.ranking;
  });
}
const averageRankCalculator = (arrs) => {
  let totalRank = 0;
  arrs.forEach((obj) =>{
    totalRank += obj.ranking;
  })
  const averageRank = totalRank / arrs.length;
  console.log(averageRank);
  return averageRank;
}

objectRanker(testArr);
averageRankCalculator(testArr);
