findMapOr

Array.findMapOr(array, predicate, mapper, fallback)

Finds the first 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 fallback if no element is found.

Example

data-first

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

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

data-last

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

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