One thing that still trips people up: `querySelector()` only returns the first match. So if you’re expecting a list, you need `querySelectorAll()` (and that gives you a NodeList, not a live HTMLCollection). I’m pretty sure kirupa has a follow-up article on `querySelectorAll()` and looping NodeLists that goes a bit deeper, but I can’t remember the exact link offhand.

One easy thing to miss: `querySelector()` / `querySelectorAll()` search within whatever element you call them on, not magically the whole page. So `someModal.querySelectorAll('button')` won’t see buttons outside that modal, which is usually what you want… until it isn’t.

I’m not sure which kirupa post you mean either, but I remember there being a follow-up about looping a `NodeList` and why it’s not “live” like an `HTMLCollection`.

`querySelectorAll()` is a snapshot, yep — if you append/remove nodes after you grab it, that NodeList just sits there looking smug while your UI changes underneath it.

I can’t remember which Kirupa post you’re thinking of either, but he definitely had a follow-up on “static NodeList vs live HTMLCollection” and the whole “looping it” thing (and why `forEach` wasn’t always there in older browsers).

One failure mode I still see: folks treat `querySelectorAll()` like it returns “the element” and try to chain straight into `classList` or whatever. It gives you a NodeList, so nothing happens unless you loop it (or pick one item with `querySelector()` / `[0]`).

And yeah, Kirupa definitely did the “static NodeList vs live HTMLCollection” follow-up at some point — I remember the bit about `forEach` being missing in older browsers and everyone writing `for (var i = 0; i < list.length; i++)` forever.
