Revision 3 of this benchmark created on

Setup

const data = new Array(1000000)
	.fill(1)
	.map((item) => Math.floor(Math.random() * 1000000))
	
const map = new Map();

data.forEach((item) => { map.set(item, Math.random()); });
const set = new Set(data);

const obj = {}

data.forEach((item) => { obj[item] = Math.random(); });

data.sort();
