Is there a `List` method in stdlib which converts `[1, 2, 3, 4]` into `[[1, 2], [2, 3], [3, 4]]`?

Is there a List method in stdlib which converts [1, 2, 3, 4] into [[1, 2], [2, 3], [3, 4]]?

list.windowed(2)

[edwardwongtl]

Thanks

.zipWithNext()

[marstran]

Or that one. zipWithNext returns a list of pairs though.

[edwardwongtl]

Oh, then zipWithNext is better in my use case

[edwardwongtl]

Thanks guys

[Dico]

Incredible that the stdlib has that tbh

[Davio]

You can also provide a transform function to zipWithNext, making it even more snazzy

@edwardwongtl Out of curiosity, what kind of functionality do you need to do that for?
