Introduction

The @supercharge/arrays package provides chainable array utilities for Node.js and JavaScript. It’s a wrapper around JavaScript arrays providing useful methods like .isEmpty(), .size(), .flatMap(), .contains(), and many more.

Installation

npm i @supercharge/arrays

Usage

Using @supercharge/arrays is pretty straightforward. The package exports a function wrapping an array or individual items as an argument. You can then fluently chain methods interacting with your data:

const { Arr } = require('@supercharge/arrays')

const hasItemsGreaterTen = Arr([1, 2, 3, 4, 5, 6])
  .map(value => value * 2) // [2, 4, 6, 8, 10, 12]
  .filter(value => value > 10) // [12]
  .isNotEmpty() // true


// Only methods, no properties
Arr([1, 2, 3]).length() // 3


// Supports callbacks for `.includes`:
Arr([1, 2, 3]).includes(value => {
  return value > 2
})

Every method in the chain returns a @supercharge/array instance. This way, you can chain further methods without leaving the fluent interface. Call .all() to retrieve the plain JavaScript array.
