Object vs Map

Benchmark created on

Setup

const iterations = 100000;

const obj = {};

for (let i = 0; i < iterations; i++) {
	const id = String(i);
	obj[id] = { id: id, [id]: id };
}

const map = new Map;

for (let i = 0; i < iterations; i++) {
	const id = String(i);
	map.set(id, { id: id, [id]: id });
}
