# "while ( counter < 11 )". Why is it not 10?

I was able to pass the test eventually but I honestly do not know why it is "while ( counter < 11 )". Why is it not 10?

script.js
```var counter = 1;
while ( counter < 11 ) {
document.write("<p>Now in loop #" + counter + "</p>");
counter += 1;
}
```

The idea of the loop is to output the numbers 1 ... through 10. The counter is being incremented each time. When counter is equal to 10, it checks the statement

```(counter < 11)
```

and it is true because 10 < 11, then it outputs the number ten. After you increment the counter variable to 11 it checks again

```(counter < 11)
```

this is false because 11 is not less than 11 and the while loop ends. You end up with 10 print statements 1 through 10. Now another way to write this would be

``` (counter <= 10)
```

This way the loop will continue as long as the counter is less than or equal to 10.

I hope this helps!

You explained that very well, thanks for the help!

If you change the counter to start at 0 (`var counter = 0`). It can be 10 like you say instead of 11.
