Why am I getting an extra circle?

I think I wrote my code correctly, but for some reason an extra circle shows up at the end.

var html = " ";

for(var i = 1; i <= 10; i += 1)  {
    html += "<div>" + i + "</div>";
} 
document.write(html);

Hello Erika.

Can you please tell us what output you want to get with your code?

We will then have a deeper look, but the first thing I notice is is that your document.write statement is outside the for loop, which does not seem to be correct.

If you provide some extra info about what you want to have in the end, I will be able to help I think.

PS I have edited your post for readability (I only wrapped the piece of code)

Vittorio,

Can you please edit her comment and wrap her code so that it will render correctly? Thanks!

Marcus Parsons Thanks for the heads-up, I must be still asleep!

No problem, and I +1'd your post because it is a good idea to get some clarity on this question! Thanks again, Vittorio!

But, I think you forgot the "javascript" keyword beside the beginning code block because even though it's in a block, the syntax still isn't being highlighted correctly.

LOL this is embarrassing.

Hello Erika.

How many times do you want it to run?

Have you tried using i<10 instead of i<=10 in the for loop?

Yes, and it runs 1 through 10 in the circles but then an 11th circle appears and it's a little higher than the first 10?

Did I put the i<=10 in the wrong space? I put it between var i = 1 and i += 1.

That is definitely the right place to put it.

It is difficult to provide a solution without knowing exactly what you are trying to do here, could you be more specific? Do you have other pieces of code related to this?

Your code should run exactly 10 times!

Have you tried using i<10 ?

What do you exactly mean by "extra circle"?

Are you linking to another file / another piece of code? Because the code you provided runs 10 times only.

Are you working with that javascript piece of code only or you have other html code as well? If you have other html code, please paste it here.

Erika, instead of attempting to post your code to the forum, you should just go ahead and post a snapshot of your workspace.

Marcus Parsons

It's really easy! :) All you gotta do is go to your Workspace, go to the top right corner, and click on the far left button that looks like a mini TV with a dot in the middle of it. Then, you click "Take Snapshot", and click on the new snapshot you created. It will open another tab/window where you'll see your name and code and stuff. Go up to the address bar, highlight that new URL, copy it, and then paste it here!

Hi Erika, Did you ever get this resolved? I forked your workspace from the snapshot, ran it and it showed the proper amount of circles. .
