The GP wasn&#x27;t saying that, as I read it. It was saying: <i>&quot;use progressive enhancement&quot;</i>.<p>When you insert new elements in the DOM with JS, you are re-rendering parts of the page. I see no other, non-invented reason that anyone <i>needs</i> to render static content with javascript. Devs do it primarily because they&#x27;re annoyed that they have to think about AJAX logic, and want to write simpler code -- at the user&#x27;s expense.
