Testcase fails though. Can't see an obvious reason. split comes back as empty always.

Here is Sayre's testcase:

function stringSplitTest()
{
  var s = "a,b"
  var a = null;
  for (var i = 0; i < 10; ++i)
    a = s.split(",");
  return a.join();
}

function stringSplitIntoArrayTest()
{
  var s = "a,b"
  var a = [];
  for (var i = 0; i < 10; ++i)
    a[i] = s.split(",");
  return a.join();
}

print(stringSplitTest())
print(stringSplitIntoArrayTest())
