Can someone help me improve my solution to this task as my code is not passing the tests

John is a famous shopkeeper who sells n items in her shop. She assigns each item a unique popularity rating in the inclusive range from 1 to n.

The shop only has one shelf, so the items are displayed array-style in a single row spanning from left to right in a random order. He wants to rearrange the items on the shelf by decreasing popularity rating such that the rating for the i item is always greater than the popularity rating of the (i + 1) item. Mary can swap any two items, i and j, in a single operation.

Specification minimumSwaps(ratings)

// Here is my solution to the problem above

function minimumSwaps(ratings) {
    var swaps = 0;
    for (var i = 0; i < ratings.length; i++) {
        for (var j = i + 1; j < ratings.length; j++) {
            if (ratings[i] == ratings[j]) {
                ratings[i] = ratings[i] + ratings[j];
            } else {
              swaps = swaps + 1;
            }
        }
    }
   return swaps;
}

minimumSwaps([4, 3, 1, 2]);
