Document.write problem

The document.write method is called undefined times

script.js 
var counter = 10;
while ( counter < 10 ) {
    document.write("<p>Now in loop #" + counter + "</p>");
    counter += 1;
}

James McIntyre,

You've initialized the counter variable at 10 and wrote a while loop that will only run while the counter is less than 10; as a result, the while loop's block will never be executed. In order to get the loop to be executed 10 times, the counter should be initialized at 0. Your code should look like this:

var counter = 0;
while ( counter < 10 ) {
    document.write("<p>Now in loop #" + counter + "</p>");
    counter += 1;
}

Hope this helps,

Charles

Hi James,

You've initially set the counter variable to 10, so your condition (counter is less than 10) will never be truthy. You need to reset the counter variable to:

var counter = 1;

And your while condition should include:

while(counter <= 10) {
...
}
