Hi all, whats the stdlib way to achieve this?
```val actual = listOf("a","b","c","d")
val expected = listOf("ab","bc","cd")```


<https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/windowed.html|https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/windowed.html>

`actual.windowed(2) { it.joinToString("") }`

Windowed accepts a transformation function , no need to map 

also found out this is a thing
```actual.zipWithNext { a, b -&gt; "$a$b" }```

Yeah. Zip with next is limited to only chunks of 2, which is fine in this case but is somewhat limiting and it actually creates a list of Pair as opposed to a list of list. Nothing wrong with that approach though

If you want list of lists, you would just do
```list.zipWithNext() {a, b -&gt; listOf(a, b)}```
but i see <@U019WDTQTS6> probably figured this out.
