flatMap

Array.flatMap(array, mapper)

Maps each element in array using the mapper function and flattens the result by one level.

Example

data-first

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

Array.flatMap([1, 2, 3], (x) => [x, x * 2]); // [1, 2, 2, 4, 3, 6]

data-last

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

pipe(
    [1, 2, 3],
    Array.flatMap((x) => [x, x * 2]),
); // [1, 2, 2, 4, 3, 6]
