Why does nothing happen?

Hi.

When I run this code, no divs appear.

HTML:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Circles</title>
  <link rel="stylesheet" href="css/styles.css">
</head>
<body id="color">
<script src="js/script.js"></script>
</body>
</html>

JavaScript:

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

Does anyone know please why there are no divs and what I should do?

Thanks

Sean :-)

Hello, all you need to do is put i after the variable declaration on line 2. Right now your loop does not 'see' a declaration for the variable i.

Change the second line of your JavaScript to

for (var i = 1; i <= 10; i += 1) {

Hope this helps.
