<div class="list"> <div class="item">1</div> <div class="item">2</div> ... <div class="item">N-1</div> <div class="item">N</div> </div>

If you have an HTML structure with elements:

<div class="list">
  <div class="item">1</div>
  <div class="item">2</div>
  ...
  <div class="item">N-1</div>
  <div class="item">N</div>
</div>

and you need, for example, to dynamically display a list of elements or process them, in JavaScript you can get all elements with the class item and work with them as an array:

const items = document.querySelectorAll('.list .item');
items.forEach((item, index) => {
  console.log(`Element ${index + 1}:`, item.textContent);
});

If it's about generating such a list on the frontend, you can use, for example, React:

function List({ count }) {
  return (
    <div className="list">
      {[...Array(count)].map((_, i) => (
        <div key={i} className="item">{i + 1}</div>
      ))}
    </div>
  );
}

Thus, the structure makes it easy to work with list elements, add, remove, or modify them dynamically.
