Array
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:
npm install @utilify/array
yarn add @utilify/array
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.
import { shuffle } from '@utilify/array';
const { shuffle } = require('@utilify/array');
Overview
Here's an overview of the functions available in the array and string utilities package:
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.
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.
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.
function compact<T>(arr: T[]): T[];
Removes "falsy" values (false, null, 0, "", undefined, NaN) from the array.
function difference<T>(arr1: T[], arr2: T[]): T[];
Returns the elements from the first array that are not in the second array.
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.
function flattenArr<T>(arr: T[], depth?: number): FlatArray<T[], number>[];
Flattens the array up to the specified depth.
function sample(str: string): string;
function sample<T>(arr: T[]): T;
Returns a random element from the array or string.
function isIterable(value: any): boolean;
Checks if the value is iterable.
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.
function rotate<T>(arr: T[], offset: number): T[];
Rotates the elements of the array offset positions.
function sanitizeArr<T>(arr: T[], values: T[], replace?: T): T[];
Removes or replaces the specified values in the array.
function shuffle<T>(arr: T[]): T[];
Shuffles the elements of the array.
function swap<T>(arr: T[], fromIndex: number, toIndex: number): T[];
Swaps the elements at positions fromIndex and toIndex.
function union<T>(...arrs: T[][]): T[];
Returns the union of multiple arrays.
function unique<T>(arr: T[]): T[];
Returns an array with unique elements.
