dropRight (Lodash Compatibility)

Use dropRight from es-toolkit

This dropRight function operates slowly due to handling null or undefined, guard parameter processing, toInteger conversion, etc.

Instead, use the faster and more modern dropRight from es-toolkit.

Returns a new array with a specified number of elements removed from the end.

const result = dropRight(array, itemsCount);

Reference

dropRight(array, itemsCount)

Use dropRight when you want to remove a certain number of elements from the end of an array and create a new array with the remaining elements.

import { dropRight } from 'es-toolkit/compat';

// Remove the last 2 elements from a number array.
dropRight([1, 2, 3, 4, 5], 2);
// Returns: [1, 2, 3]

// Remove the last 1 element from a string array.
dropRight(['a', 'b', 'c'], 1);
// Returns: ['a', 'b']

// If the number to remove is not specified, the default value 1 is used.
dropRight([1, 2, 3]);
// Returns: [1, 2]

null or undefined are treated as empty arrays.

import { dropRight } from 'es-toolkit/compat';

dropRight(null, 2); // []
dropRight(undefined, 2); // []

Parameters

• array (ArrayLike<T> | null | undefined): The array to remove elements from.
• itemsCount (number, optional): The number of elements to remove from the end of the array. Default is 1.

Returns

(T[]): Returns a new array with itemsCount elements removed from the end.
