Very confused by this question...

Hey team, I was doing a challenge and answered by placing a condition inside of the parenthesis: while ( counter < 10 ).... It was incorrect. Why, what did I miss or do wrong? Thanks!

Here is the challenge:

This is a nearly complete while loop, but something is missing. The loop should run 10 times, but it's not working at all. Can you fix it?

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

Since the counter starts at one, the condition "counter < 10" will only run nine times. To run ten times the condition should be "counter <= 10".

It would also work with "counter < 11", but the intention would not be as clear.
