Benchmark: Array iteration for while etc

Script Preparation code:

var testArray = new Array(1024);
var sum = 0;

Tests:

Simple for
for (var c=0; c<testArray.length; c++) { sum += c; }
While
var c = 0; while (c<testArray.length) { sum += c; c++; }
While + 1
var c = 0; while (c<testArray.length) { sum += c; c += 1; }
For +1
for (var c=0; c<testArray.length; c+=1) { sum += c; }
Reverse for
for (var c=testArray.length; c>0; c--) { sum += c; }
Cached for
var length = testArray.length; for (var c = 0; c<length;c++) { sum += c; }
