type window

Returns a transformer that produces windows/collections of windowSize size, each window starting skipAmount of elements after the previous, and optionally collected by a custom reducer.

example

Stream.of(1, 2, 3, 4, 5, 6)
.transform(Transformer.window(3))
.toArray()
// => [[1, 2, 3], [4, 5, 6]]
