This can also be a side product for code blocks being expressions instead of statements.

In rust for example they are, so it's not rare to see functions like:

fn add_one(x: i32) -> i32 {
    x+1
}

This lets you do amazing things like:

let x = if y < 0.0 {
    0.0
} else {
    y
}

which is the same as x = y < 0.0 ? 0.0 : y

But is much better for more complex logic. So you can forget about chaining 3-4 ternary operations in a single line.
