Benchmark: new empty object vs constant vs frozen constant

Script Preparation code:

var empty={};
var frozen=Object.freeze({});
var fnNew=()=>({});
var fnConstant=()=>empty;
var fnFrozen=()=>frozen;

Tests:

empty
const arr=new Array(500).fill().map(()=>({}));
constant
const arr=new Array(500).fill().map(()=>empty);
frozen
const arr=new Array(500).fill().map(()=>frozen);
fn new
const arr=new Array(500).fill().map(fnNew);
fn constant
const arr=new Array(500).fill().map(fnConstant);
fn frozdn
const arr=new Array(500).fill().map(fnFrozen);
