Question: I need your help.

I'd like to create a function that would add some zeros in front of a number. The maximum numbers of digits that the total string should have is 6. Here are examples:

```
     9 -> 000009
    14 -> 000014
   230 -> 000230
  1459 -> 001459
 21055 -> 021055
987632 -> 987632 (Do nothing, there's already 6 digits)

```

Answer: 
Recursive solution just for the heck of it:

```
function padNumberString(numberString) {
    if (numberString.length >= 6) {
        return numberString;
    }
    return padNumberString('0' + numberString);
}

```
I have been using the SugarJs API for a long time and their padding feature works great. 

<http://sugarjs.com/api/Number/pad>

```
(9).pad(6, true) --> 000009
(14).pad(6, true) --> 000014

```

etc...
