Thanks for the explanation! So it's also equivalent to: ```fun prepareAndSendMultiple(listMessages: ...

# arrow

Thanks for the explanation! So it's also equivalent to:

fun prepareAndSendMultiple(listMessages: List<Message>, connectionStringKey: String, queueKey: String): IO<Unit> =
         listMessages.parTraverse { message ->
            prepareAndSend(message, connectionStringKey, queueKey) // returns IO<Unit>
        }.unit()

?

Yes

[Kristian]

Perfect. Indeed then there is no need to wrap it in an effect here. 🙂

[simon.vergauwen]

You get unit() for free if you can implement map 😉

[Kristian]

That's very kind 😛
