I often see people write that

when

without an argument is a replacement for an

if-else-if

ladder. But why particularly the argument-less one? Isn't it also a replacement for

if-else-if

when it has an argument?

I think

when

looks nicer. What's more, in the case of

if (a > 0) {}
else if (b > 0) {}
else {}

it can be a little bit more difficult to pass one variable.

What I mean is

yes, but

if

does not take an argument, so the comparison with the zero-argument

when

is a closer match

That makes a lot of sense, thank you
