import { slidingWindows } from "https://deno.land/std@0.218.2/collections/mod.ts";
Generates sliding views of the given array of the given size and returns a new array containing all of them.
If step is set, each window will start that many elements after the last window's start. (Default: 1)
If partial is set, windows will be generated for the last elements of the collection, resulting in some undefined values if size is greater than 1.
