Benchmark: Can JavaScript benefit from the ECS pattern 3

Script Preparation code:

class Point {
  constructor(x, y) {
    this.x = x;
    this.y = y;
    this.health = 100;
  }

  tick() {
    this.x += 2;
    this.y += 2;
    this.health -= 1;
  }
}

var pointClasses = [];
var pointObjectsA = new Int32Array( 1000000 );
var pointObjectsB = new Int32Array( 1000000 );
var pointObjectsC = new Int32Array( 1000000 );

for (let i = 0; i < 1000000; i++) {
  pointClasses.push(new Point(0, 0));
  pointObjectsA[ i ] = 0;
  pointObjectsB[ i ] = 0;
  pointObjectsC[ i ] = 100;
}

Tests:

OO-style
let i; for ( i = 0; i < 1000000; i++ ) pointClasses[ i ].tick();
ECS-style
let i; for ( i = 0; i < 1000000; i++ ) { pointObjectsA[ i ] += 2; pointObjectsB[ i ] += 2; pointObjectsC[ i ] = 100; }
