Occasionally, users may unintentionally activate the Caps Lock, leading to a failed password authentication attempt.
Displaying a message in such a scenario could significantly enhance the user experience.
Do you know how to detect the status of the caps lock?

The getModifierState() function in JavaScript is used to check the state of a modifier key during a keyboard event.

A modifier key usually means one of the shift, ctrl, alt, and caps lock.

This is the basic usage of the getModifierState() function to detect the status of the caps lock key.
You can use a similar logic to check for other modifier keys.
