Benchmark: new versus raw object creation

Script Preparation code:

let entityId = 0;

function Entity () {
	this.id = entityId++;
	this.x = 0;
	this.y = 0;
  	this.angle = 0;
}

function createEntity () {

	const obj = {
		id : entityId++,
		x : 0,
		y : 0,
		angle : 0,
    }

	return obj;
}

Tests:

new
const obj = new Entity (); obj.angle = obj.x + obj.y;
{}
const obj = createEntity (); obj.angle = obj.x + obj.y;
