function option.toUndefined
import { option } from "https://deno.land/x/fun@v.2.0.0-alpha.11/mod.ts";
const { toUndefined } = option;

toUndefined returns either undefined or the inner value of an Option. This is useful for interacting with code that handles undefined but has no concept of the Option type.

Examples

Example 1

import * as O from "./option.ts";

const result1 = O.toUndefined(O.none); // undefined
const result2 = O.toUndefined(O.some(1)); // 1

Returns

A | undefined
