Function unwrapOrElse

Safely get the value out of a Maybe by returning the wrapped value if it is Just, or by applying orElseFn if it is Nothing.

This is useful when you need to generate a value (e.g. by using current values in the environment – whether preloaded or by local closure) instead of having a single default value available (as in unwrapOr).

import Maybe from 'true-myth/maybe';

// You can imagine that someOtherValue might be dynamic.
const someOtherValue = 99;
const handleNothing = () => someOtherValue;

const aJust = Maybe.just(42);
console.log(Maybe.unwrapOrElse(handleNothing, aJust));  // 42

const aNothing = nothing<number>();
console.log(Maybe.unwrapOrElse(handleNothing, aNothing)); // 99
