import { partition } from "https://deno.land/x/itertools@v1.1.2/more-itertools.ts";
Returns a 2-tuple of arrays. Splits the elements in the input iterable into either of the two arrays. Will fully exhaust the input iterable. The first array contains all items that match the predicate, the second the rest:
>>> const isOdd = x => x % 2 !== 0;
>>> const iterable = range(10);
>>> const [odds, evens] = partition(iterable, isOdd);
>>> odds
[1, 3, 5, 7, 9]
>>> evens
[0, 2, 4, 6, 8]
