Get the same key for the same sequence of values!
- 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
$ npm i keyalesceimport keyalesce from 'keyalesce'
const hangouts = new Set()

hangouts.add(createHangoutKey(person1, person2))
const didTheyHangOut = (person1, person2) =>
hangouts.has(createHangoutKey(person1, person2))
hangOut(`Tomer`, `Samuel`)
hangOut(`Tomer`, `Amanda`)
