findMapLastOrElse

Array.findMapLastOrElse(array, predicate, mapper, callback)

Finds the last element in array that satisfies the provided predicate function and applies the mapper function to it, returning a new array with the mapped element, or the result of calling callback with the array if no element is found.

Example

data-first

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

Array.findMapLastOrElse(
    [1, 2, 3, 4],
    (x) => x > 10,
    (x) => x * 10,
    (arr) => arr.length,
); // 4

data-last

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

pipe(
    [1, 2, 3, 4],
    Array.findMapLastOrElse(
        (x) => x > 10,
        (x) => x * 10,
        (arr) => arr.length,
    ),
); // 4
