Accidentally, seems harder. It kinda smells for people to intentionally make it not popular by actively working against fame, or something like that..
It's not harder; it's the only thing that works for tools. Tools cannot be good for long because of marketing. Marketing is the thin layer of paint over the Ferrari. Very nice paint, but if the car doesn't work or go very fast very quickly then that's that.
$(el).is(':hidden')
!(el.offsetWidth || el.offsetHeight || el.getClientRects().length)
$(".alert").hide();
for (const el of document.querySelectorAll(".alert")) {
el.style.display = 'none';
} $(el).is(':hidden')
el.hidden
document.querySelectorAll(".alert").forEach(el => el.hidden = false);
Unfortunately, I usually don't keep the whole codebase in my head (including libraries), so I often don't know the reason.
The more general point is that I don't want to have to know, because the mechanism of how it is hidden is not what I care about.

Yes, it's more than three times as long as the jQuery variant.
DOM APIs are quite literally 90s era Java-style APIs.
While DOM APIs have pulled in a few niceties over the years, some of them are really anemic (e.g. querySelectorAll does not return a proper Array-like object). Worse is combining them. Almost every API is a single-shot tedious step-by-step chore.
