jQuery is designed not to fail. So if there's no `.box` on the page, jQuery will not do anything.
`querySelector` may return null, so `$('.box').hidden` will hard break your page if you're not careful enough
2. `$('.box').hide()` is just one such example.
The hilarious https://youmightnotneedjquery.com/ shows that jQuery remains more consistent, concise, and composable than most things in modern browser APIs
Also, do you know if there is a jQuery-like that actually throws exceptions? Having `$('.box').hide()` tell me there is no `.box` would be pretty useful.
Hide Show
```
$(".box").hide();
$(".box").show();
vs
document.querySelector(".box").style.display = "none";
document.querySelector(".box").style.display = "block";
``` Both work. The first is more clear
