Benchmark Run Result for: Caching length property vs getting it each time in the loop

Test name	Executions per second
123456'and(selectfrom(select+sleep(2))a//union/*/select+1)='	123456.0 Ops/sec
123456	123456.0 Ops/sec

Script Preparation code:

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

Tests:

Cache length
var arrLen = arr.length; var sum = 0; for (var i = 0; i < arrLen; i++){ sum = arr[i]; }
Do not cache
var sum = 0; for (var i = 0; i < arr.length; i++){ sum = arr[i]; }
