When using a password input, detecting if a user has their keyboard’s caps lock turned on can be challenging. Users may not realize their caps lock is on and input an incorrect password, leading to frustration. To address this issue, developers can use the `KeyboardEvent`’s `getModifierState` method to detect if the caps lock is on. This method provides insight into the user’s keyboard during key-centric events. By employing this method, developers can warn the user when their caps lock is on, helping to prevent incorrect password entries. The `getModifierState` method is a valuable tool for improving the user experience, providing developers with a way to address the issue of caps lock detection in password inputs.
