new Array() vs Object.create(Array.prototype)

Question

A naive confusion:

var arr1 = new Array();
var arr2 = Object.create(Array.prototype);
//Inserting elements in \"both arrays\"
arr1[0] =0;
arr1[9] =9;
arr2[0]         


        

Answer 1

var arr1 = new Array(); is the proper way to instantiate an array. It is the same as using the array literal: var arr1 = [];
