Array 2.0.0

The array utility functions provide a variety of methods to manipulate and transform arrays and strings. They help simplify common operations such as splitting, flattening, shuffling, and finding differences between arrays, among others.

Installation

To install the array utility functions, use one of the following commands depending on your package manager:

bash

npm install @utilify/array

bash

yarn add @utilify/array

bash

pnpm add @utilify/array

After installation, you can import the functions into your project using ESM or CJS.

Usage

This library supports both the ESM and CJS module systems.

typescript

import { shuffle } from '@utilify/array';

javascript

const { shuffle } = require('@utilify/array');

Overview

Here's an overview of the functions available in the array and string utilities package:

after

function after(str: string, index: number): string;
function after<T>(arr: T[], index: number): T[];

Returns the elements of the array or string after the index index.

before

function before(str: string, index: number): string;
function before<T>(arr: T[], index: number): T[];

Returns the elements of the array or string before the index index.

chunk

function chunk(str: string, size: number): string[];
function chunk<T>(arr: T[], size: number): T[][];

Splits the array or string into smaller chunks of size size.

compact

function compact<T>(arr: T[]): T[];

Removes "falsy" values (false, null, 0, "", undefined, NaN) from the array.

difference

function difference<T>(arr1: T[], arr2: T[]): T[];

Returns the elements from the first array that are not in the second array.

first

function first(str: string, count?: number): string;
function first<T>(arr: T[], count?: number): T[];

Returns the first count elements of the array or string.

flattenArr

function flattenArr<T>(arr: T[], depth?: number): FlatArray<T[], number>[];

Flattens the array up to the specified depth.

isIterable

function isIterable(value: any): boolean;

Checks if the value is iterable.

last

function last(str: string, count?: number): string;
function last<T>(arr: T[], count?: number): T[];

Returns the last count elements of the array or string.

rotate

function rotate<T>(arr: T[], offset: number): T[];

Rotates the elements of the array offset positions.

sample

function sample(str: string): string;
function sample<T>(arr: T[]): T;

Returns a random element from the array or string.

sanitizeArr

function sanitizeArr<T>(arr: T[], values: T[], replace?: T): T[];

Removes or replaces the specified values in the array.

shuffle

function shuffle<T>(arr: T[]): T[];

Shuffles the elements of the array.

swap

function swap<T>(arr: T[], fromIndex: number, toIndex: number): T[];

Swaps the elements at positions fromIndex and toIndex.

union

function union<T>(...arrs: T[][]): T[];

Returns the union of multiple arrays.

unique

function unique<T>(arr: T[]): T[];

Returns an array with unique elements.
