Test name	Executions per second

function	85236.5 Ops/sec

Script Preparation code:

class Vector {
  constructor(x, y) {
    this.x = x
    this.y = y
  }
}

function createVector(x, y) {
  return { x, y }
}

window.Vector = Vector
window.createVector = createVector

Tests:

constructor
for (let x = 0; x < 100; x++) { for (let y = 0; y < 100; y++) { new Vector(x, y) } }
function
for (let x = 0; x < 100; x++) { for (let y = 0; y < 100; y++) { createVector(x, y) } }
