Action + return + if on single line?

Ruby
1

Is it possible to have an if-statement that both do something and
returns from a method - in one single line? I often have code where an
action has to be performed conditionally and then exit/return/break, and
an if/end-block seems like such a waste.

Best regards,

return “string”.upcase if true

There’s good old
something and return if condition

If something doesn’t return a value that evaluates to true, you can
always do something like
[something] and return if condition

Ah, of course. And that works equally good with break and next as well,
didn’t know that! Thanks!!
