I followed the video and am seeing nothing in the preview

var html = '';

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

html += '<div>' + i + '</div>'; } document.write(html);

You have a semicolon in the last expression (i += 1;). Only the first two need it to separate the expressions. Get rid of that one right before the closing parentheses and you're good.

var html = '';

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