Hi, how do i sort this array of objects and add a new attribute to each object called score, giving each of them a score between 1 and 6, if some objects have the same score the next score needs to increment by the number of value with the same score.
This is an example of how i need the output to be. Thanks

>Solution :
Sort, then assign the index as the score, unless the previous entry is equal, in that case take over their score:
const byAward = (a, b) => a.awards - b.awards;
winners.sort(byAward);
winners.forEach((winner, index) => {
if (index === 0 || byAward(winner, winners[index - 1]) !== 0)
winner.score = index + 1;
else
winner.score = winners[index - 1].score;
});
