partitionMap
import { partitionMap } from "https://raw.githubusercontent.com/baetheus/fun/main/option.ts";Map and partition over the inner value of an Option at the same time. If the option passed is None then the result is [None, None], otherwise Right will result in [Some, None], and Left will result in [None, Some].
@example
import * as O from "./option.ts";
import * as E from "./either.ts";
const partitioner = (n: number) => n > 0 ? E.right(n) : E.left(n * -1);
const partitionMap = O.partitionMap(partitioner);
const result1 = partitionMap(O.some(1)); // [Some(1), None]
const result2 = partitionMap(O.some(-1)); // [None, Some(1)]
const result3 = partitionMap(O.none); // [None, None]
