I do not understand the concept of "you logged 1 number but you need 12" can some please explain this to me?

Am i setting up the loop correctly to get all even number up to 24?

script.js 
var html = '';
var even

for (var i = even; i < 25; i += 2) {
  html += '<div>' + i + '</div>';
}
console.log(html);
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript Loops</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

The console.log will need to be in the loop because it is what you want to repeat over and over. For this challenge, you don't actually need to declare any other variables. 'i' does need to start at 2 though. Also, in this challenge, you don't need to add html to the page. just console.log. so you can remove those new div tags entirely.

for ( var i = 2; i < 25; i += 2) { 
  console.log(i)
}
