## Change a result of BubbleSort

Hi! After I used the BubbleSort algorithm to sort by 10 previously generated random numbers, I would like to display them but with a space between the comma and a number. But is it even possible to change the result after the algorithm?
Code:
```/*i've created these random numbers before*/
var a = [number1, number2, number3, number4, number5, number6, number7,number8, number9, number10];

function bubbleSort(a)
{
var swapped;
do {
swapped = false;
for (var i=0; i < a.length-1; i++) {
if (a[i] > a[i+1]) {
var temp = a[i];
a[i] = a[i+1];
a[i+1] = temp;
swapped = true;
}
}
} while (swapped);
}
bubbleSort(a);

document.getElementById('container1').innerHTML = 'The random numbers are: ' + a;
}```
The result looks p.e: 23,34,657,5643...
But it should look like: 23, 34, 567, 5643...

2. Try adding something like
Code:
```var resultStr="";
for (var i=0; i < a.length; i++) {
resultStr+= a[i];
resultStr+=(i < (a.length - 1)): ", ":""; }
...
...     'The random numbers are: ' + resultStr```

Are you sure about this code? I recive an error message because of your 4. line (because of the ':') but I do not learn JavaScript long enough to see where the mistake is.

4. Sorry 'bout that. The first colon on line 4 should be a question mark.

5. Why you not using the .sort() method of an array?

Code:
```var a = [9, 1, 8, 2, 7, 3, 6, 4, 5, 10];
a.sort( function(a,b){ return a - b; } ); // sorts 0 to nth, using b-a reverses that < and > can be used in alpha sorts too.
a.join(", ");
console.log("array = "+a);```
Will sort the array in order and also the final part joins the array in to a string and puts a comma and a space after the comma.

Job done, no bubble sorting needed (which is costly in processing time)
