As demonstrated (rather poorly) in the documentation, if the final expression in the if
has type unit
then the else
is optional. Thus your code can simply become:
if some_condition then expr
문제
I find myself doing this occasionally:
if some_condition then
expr
else
()
Is there a nicer way to do this? It seems there should be a one-liner. (Running it all into one line doesn't count. By "one-liner" I mean "something which in one line indicates more clearly my intentions.")
