My goal is to turn 

```
['sara', 'mike', 'sara','sara','Jon'] 

```

into 

```
'sara', 'mike', 'sara(1)','sara(2)' 'Jon'

```

Ive seen some solutions when counting the total number of duplicates, however, couldnt find anything for what I am trying to do..

ps. I cannot use sort() as the names should stay where they were in the original array..

I tried using a regular for loop but nothing really worked, I also think a map approach would probably be good, but cant figure out how to do that.

Thank you!

EDIT:

I actually came up with this here:

```
function words(arr){
  var result=[];
  var count=0;
 for (var i=0; i<arr.length; i++){
    if (result.indexOf(arr[i])==-1){
    result.push(arr[i]);    
    }
    else {
        count++;
        result.push(arr[i]+"("+count+")");
    }

 }
 return result.join(',');
}

words(['sara', 'mike', 'sara','sara','Jon'] );

```

and it works except it returns 'sara,mike,sara(1),sara(2),Jon' instead of 'sara','mike,'sara(1)','sara(2)','Jon'

Anyone knows how to change that? I tried join, split etc already..
