getOrElse

function Object.getOrElse<
    T extends object,
    U extends keyof AllUnionFields<T>,
    V,
>(
    target: T,
    key: U,
    orElse: (target: NoInfer<T>) => V,
): Exclude<AllUnionFields<T>[U] | V, null | undefined>

Returns the value of key property from target object, or the result of calling orElse function with target if not found or nullish.

Example

data-first

import { Object } from "@monstermann/object";

Object.getOrElse({ a: 1, b: 2 }, "a", () => 0); // 1
Object.getOrElse({ a: 1, b: 2 }, "c", (obj) => Object.keys(obj).length); // 2

data-last

import { Object } from "@monstermann/object";

pipe(
    { a: 1, b: 2 },
    Object.getOrElse("a", () => 0),
); // 1

pipe(
    { a: 1, b: 2 },
    Object.getOrElse("c", (obj) => Object.keys(obj).length),
); // 2
