Bug Report for https://neetcode.io/problems/sql-delete-where

Please describe the bug below and include any steps to reproduce the bug or screenshots if possible.

In the SQL for beginners course, the DELETE WHERE section has below sql command.
DELETE FROM users
WHERE username = NULL;

NULL is unknown. It will not delete anything as unknown will not be found when you use =.

The correct command would be the following (using the IS operator)
DELETE FROM users
WHERE username IS NULL;
