1D vs 2D Array (v2)

Revision 2 of this benchmark created on

Setup

var arrDim = 10000;
var actualArrDim = 10;

class Foo {}

var oneDimArr = new Array(arrDim).fill(new Foo());
var twoDimArr = new Array(actualArrDim).fill(new Array(Math.round(arrDim / actualArrDim)).fill(new Foo()));
console.log(twoDimArr)
