    target: readonly T[],
    predicate: (
        value: NoInfer<T>,
        index: number,
        target: readonly NoInfer<T>[],
    ) => boolean,
    or: V,
): Exclude<T, null | undefined> | V

import { Array } from "@monstermann/array";

Array.findLastOr([1, 2, 3, 4], (x) => x > 10, 0); // 0

data-last

import { Array } from "@monstermann/array";

pipe(
    [1, 2, 3, 4],
    Array.findLastOr((x) => x > 10, 0),
); // 0
