Benchmark: Tuple vs Object vs Class V4

Script Preparation code:

const N = 1000000;

class Tuple {
  first;
  second;
  constructor(first, second) {
    this.first = first;
    this.second = second;
  }
}

Tests:

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