takeRight (Lodash compatibility)

Please use takeRight from es-toolkit

This takeRight function operates slowly due to handling null or undefined.

Please use the faster and modern takeRight from es-toolkit instead.

Takes a specified number of elements from the end of an array.

const result = takeRight(array, count);

Reference

takeRight(array, count)

Use takeRight when you want to create a new array by taking a specified number of elements from the end of an array. If the requested count is greater than the array length, returns the entire array.

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

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

// Take the last 3 elements from a string array.
takeRight(['a', 'b', 'c'], 2);
// Returns: ['b', 'c']

// When requested count is greater than array length
takeRight([1, 2, 3], 5);
// Returns: [1, 2, 3]

// Request 0 elements
takeRight([1, 2, 3], 0);
// Returns: []

// Request negative number
takeRight([1, 2, 3], -1);
// Returns: []

null or undefined is treated as an empty array.

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

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