Introduction

The @supercharge/set package provides an improved Set implementation.

• aligned with the Array class instead of Map
• provides helpful methods like .map(callback), .filter(callback), .find(callback), .isEmpty(), and many more.
• compares values for deep equality and not reference
• it’s the Set class JavaScript should have shipped

Installation

npm i @supercharge/set

Quick Usage Overview

Using @supercharge/set is pretty straightforward. The package exports a Set class providing all methods to interact with the set.

const Set = require('@supercharge/set')

const users = new Set()

users.isEmpty() // true

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

users.isNotEmpty() // true

const usernames = users.map(user => {
  return user.name
})
// [ 'Marcus', 'Norman', 'Christian' ]

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