keyalesce

Get the same key for the same sequence of values!

Features

• Simple: a single function that takes an array and returns a key
• Tiny: 580 bytes gzipped!
• Performant: maintains a regularly pruned internal trie of the value sequences

When would I use this and how does it work?

Install

$ npm i keyalesce

Usage

import keyalesce from 'keyalesce'

const hangouts = new Set()

const createHangoutKey = (person1, person2) =>
  keyalesce([person1, person2].sort())
const hangOut = (person1, person2) =>
  hangouts.add(createHangoutKey(person1, person2))
const didTheyHangOut = (person1, person2) =>
  hangouts.has(createHangoutKey(person1, person2))

hangOut(`Tomer`, `Samuel`)
hangOut(`Tomer`, `Amanda`)

console.log(didTheyHangOut(`Tomer`, `Samuel`))
console.log(didTheyHangOut(`Samuel`, `Tomer`))
//=> true
//=> true

console.log(didTheyHangOut(`Tomer`, `Amanda`))
console.log(didTheyHangOut(`Amanda`, `Tomer`))
//=> true
//=> true

console.log(didTheyHangOut(`Samuel`, `Amanda`))
