While vs For loop with count and Array.methods (v60)

Revision 60 of this benchmark created by svenskanda on

Description

no Array.shift() vs Array.shift/Array.push

Setup

var j = 0, k = 0;
    
    function setArr()
    {
    arr = [];
    for(var i=0;i<1000;i++) 
    {
       val = Math.ceil( Math.random() * 10 );
       arr[i] = val;
    }
    return(arr);
    }
