Benchmark: Tuple vs Object vs Class V3

Script Preparation code:

const N = 1000000;

class Tuple {
  first;
  second;
  constructor(first, second) {
    this.first = first;
    this.second = second;
  }
}

function createArrayTuple(first, second) {
  return [first, second];
}

function createObjectTuple(first, second) {
  return { first, second };
}

Tests:

Array
const xs = []; for (let i = 0; i < N; i++) { xs.push(createArrayTuple(i, 0)); }
Object
const xs = []; for (let i = 0; i < N; i++) { xs.push(createObjectTuple(i, 0)); }
Class
const xs = []; for (let i = 0; i < N; i++) { xs.push(new Tuple(i, 0)); }
