`$log.i(log)`	Info	Recording the ordinary flow of behavior
`$log.w(log)`	Warning	Warning about a potential problem
`$log.e(log)`	Error	Recording errors and exceptions

Example

$log.d("버튼 클릭됨");

const data = $vm.getDSValue("userList");
$log.i("데이터 건수: " + data.length);

if (data.length === 0) {
  $log.w("데이터가 없습니다. 조회를 먼저 실행하세요.");
}

try {
  // Handle the logic
} catch (e) {
  $log.e("오류 발생: " + e.message);
}
