Rust for JavaScript Developers – Functions and Control Flow

Re:Rust for JavaScript Developers – Functions and Control Flow by skocznymroczny on Monday July 06, 2020 @02:48AM (#23745336)

I dislike the ternary operator in languages like C++. And many languages copy-paste it because they are used to it. I much prefer the more literal and reversed form in Python.

Instead of:

int salary = isEmployed() ? 2000 : 0

I prefer:

int salary = 2000 if isEmployed() else 0

Yes, it also makes the larger example somewhat readable:

    func calculate_tax(income):
        return 0 if income < 10 else 20 if income < 50 else 50

I love that idea, but I still prefer it’d read the same as an if. Meaning the condition first and the false case last.

Rust implements this:

    let foo = if is_employed() { 2000 } else { 0 }
