why does this compile : `listOf(1,2,3,4).fold("") ...

why does this compile : listOf(1,2,3,4).fold("") { acc, i -> acc } but this doesn't listOf(1,2,3,4).fold("") { acc, i -> { acc } } Or put another way : How do I write fold that is multi-statements and has some variables?

Because your second version is returning a lambda instead of a String.

[ephemient]

just like any other lambda,

listOf(1, 2, 3, 4).fold("") { acc, i ->
    statement1
    statement2
}

(or separate them with semicolons, but why would you do that)

@Ruckus Yes.. I see that. Makes sense now. thanks

@ephemient I could have sworn I tired that and got the same error. but clearly I didn't cuz it works 🙂 thanks
