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(), .length(), .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 users = Arr.from([])

users.isEmpty()
// true

users
  .push({ id: 1, name: 'Marcus' })
  .push({ id: 2, name: 'Norman' })
  .push({ id: 3, name: 'Christian' })

users.isNotEmpty()
// true

users.length()
// 3

const usernamesArray = users
  .map(user => user.name)
  .toArray()
// [ 'Marcus', 'Norman', 'Christian' ]

const marcus = users.find(user => {
  return user.name === 'Marcus'
})
// { id: 1, name: 'Marcus' }

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.
