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)); } for (let i = 0; i < N; ++i) { xs[i].second += i; }
Object
const xs = []; for (let i = 0; i < N; ++i) { xs.push({ first: i, second: 0 }); } for (let i = 0; i < N; ++i) { xs[i].second += i; }
Tuple
const xs = []; for (let i = 0; i < N; ++i) { xs.push([i, 0]); } for (let i = 0; i < N; ++i) { xs[i][1] += i; }
