I couldn't find any information about the usage of 'response' in the documentation. What is it used for?

console.log(loginForm.response.value); It has always been an empty object.
On the login page, I didn't fill anything in and directly clicked the submit button.
The page shows error messages, but the response is still an empty object.

The response property can be use to show an error, info or success message to the user. It is not perfectly documented but here is some info: https://modularforms.dev/qwik/guides/throw-form-errors

You can manually set the Response data.
