Setup

var arr = [];
    for(var i = 0; i < 1000; i++) arr[i]=i;

Test runner

Ready to run.

Testing in
TestOps/sec
forEach
arr.forEach(function(){});
ready
loop
for(var i = 0, l = arr.length; i < l; i++){ }
ready
while
var j=arr.length;

while(--j>0){}
ready
for 2
var i = -1;
var len = arr.length
for (; ++i < len;) {
   
}
ready
for 3
for (var i = arr.length-1; i > -1; i--) {}
ready
for 4
for (i = arr.length - 1; i >= 0; i--) {
    
}
ready
while 2
var i = arr.length;
while(i--) {

}
