findMapLastOrThrow

Array.findMapLastOrThrow(array, predicate, mapper)

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 throws an error if no element is found.

Example

data-first

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

Array.findMapLastOrThrow(
    [1, 2, 3, 4],
    (x) => x > 2,
    (x) => x * 10,
); // [1, 2, 3, 40]

data-last

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

pipe(
    [1, 2, 3, 4],
    Array.findMapLastOrThrow(
        (x) => x > 2,
        (x) => x * 10,
    ),
); // [1, 2, 3, 40]
