Script Preparation code:
var array = Array.from({length:10000},() => (()=>([1e7]+-1e3+-4e3+-8e3+-1e11).replace(/[018]/g,a=>(a^Math.random()*16>>a/4).toString(16)))()) var set = new Set(array); var object = Object.fromEntries(array.map((k) => [k,true])) var map = new Map(array.map((k) => [k,true])); var randomAccess = [...array].sort(() => Math.random() -0.5).slice(0,1000)
Tests:
Set
for (const k of randomAccess) set.has(k)
Object
for (const k of randomAccess) object[k]
Map
for (const k of randomAccess) map.get(k)
Array
for (const k of randomAccess) array.includes(k)
