dropRight (Functional Programming)

Creates a function that drops values from the end of an array. Use it with pipe.

const result = pipe(array, dropRight(count));

Usage

dropRight removes the last count values from the piped array.

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

pipe([1, 2, 3, 4], dropRight(2)); // => [1, 2]

Parameters

• count (number): The number of values to drop from the end.

Returns

((array: readonly T[]) => T[]): A function that maps a readonly T[] to the remaining values.
