getOrElse

import { getOrElse } from "https://raw.githubusercontent.com/baetheus/fun/main/option.ts";

getOrElse operates like a simplified fold. One supplies a thunk that returns a default inner value of the Option for the cases where the option is None.

@example

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

const toNumber = O.getOrElse(() => 0);

const result1 = toNumber(O.some(1)); // 1
const result2 = toNumber(O.none); // 0

function getOrElse(onNone: () => B): (ua: Option) => B;

getOrElse(onNone: () => B): (ua: Option) => B
