Benchmark: Caching length property (internal and external) vs getting it each time in the loop

Script Preparation code:

var arr = [];
var count = 1000;
for(var i = 0; i<count; i++)
{
  arr.push(i);
}

Tests:

Cache length (external)
var arrLen = arr.length; var sum = 0; for (var i = 0; i < arrLen; i++){ sum = arr[i]; }
No cache
var sum = 0; for (var i = 0; i < arr.length; i++){ sum = arr[i]; }
Cache length (internal)
var sum = 0; for (var i = 0, arrLen = arr.length; i < arrLen; i++){ sum = arr[i]; }
