Can you spot the form bug?

<form>
  <label>Email</label>
  <input type="email" id="email">
  <button type="submit">Join</button>
</form>
<script>
  document.querySelector('form').addEventListener('submit', (e) => {
    if (!email.value.includes('@')) alert('invalid');
  });
</script>

Reply with what is broken and how you would fix it.

The email variable is used but not declared.

Guess is in, noted. Answer drops later today, staying quiet until then.
