Alright, spicy opinion time: I think, the ! operator is dumb.

It's yet another symbol with a meaning, which people have to learn.

And it's easy to overlook, especially in languages with parentheses in their if-conditions:

if (!list.isEmpty()) { ... }

I think that just a .not() method on Booleans is cooler:

if (list.isEmpty().not()) { ... }

You can do this in Rust, which is where I have that idea from: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=dedb71bd84243c78ee0afad0f30b80c3
