    With the help of recursion it solves pretty easy:

    function calcOperations(row, left, right) {
    if (left >= right) return 0;

    var leftCode = row.charCodeAt(left);
    var rightCode = row.charCodeAt(right);
    var diff = Math.abs(rightCode - leftCode);
    return diff + calcOperations(row, left + 1, right - 1);
}
