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
Mathematics themselves are essentially tons of symbols that people have to learn, tbf.
I personally never had any trouble looking at the negation operator, and find the
.not()postfix cumbersome.To be fair, mathematics also uses single-character variable names
