Usage

reverse returns a new array with the values of the piped array in reverse order. It does not mutate the input array.

typescript

import { pipe, reverse } from 'es-toolkit/fp';

const array = [1, 2, 3];

pipe(array, reverse()); // => [3, 2, 1]
array; // => [1, 2, 3]

This function takes no arguments; call it as reverse().

((array: readonly T[]) => T[]): A function that maps a readonly T[] to a reversed copy.
