Data access (v2)

Revision 2 of this benchmark created on

Setup

const obj = {
	a: 1,
	b: 2,
	c: 3,
	d: 4,
	e: 5,
}

const map = new Map();
map.set("a", 1);
map.set("b", 2);
map.set("c", 3);
map.set("d", 4);
map.set("e", 5);


const frozen = Object.freeze({
	a: 1,
	b: 2,
	c: 3,
	d: 4,
	e: 5,
})

const arr = [1, 2, 3, 4, 5]

const typed = new Uint8Array(arr)
