How to display Jade block in index.html in a loop?

Question

Pug

Hello! I decided to finally start using Jade for layout of html files.
I immediately ran into the problem of outputting a block in a loop. Previously, I just used this construction to display blocks of the same type:

<?php
$n = 6;
  for ($i=0; $i < $n; $i++) { 
  include('assets/item-n.html');
}
?>

After digging through the docs, I realized that in my case, include should be replaced with extend. But how to display it in a cycle, I did not figure it out. It would be ideal if someone explained how to generate unique content in these blocks.
