No Need to Convert Carbon

If you're performing whereDate() and check today's records, you can use Carbon's now() and it will automatically be transformed to date. No need to do ->toDateString().

1// Instead of
2$todayUsers = User::whereDate('created_at', now()->toDateString())->get();
3// No need to convert, just use now()
4$todayUsers = User::whereDate('created_at', now())->get();
