Why do we need to use both focus(confirmPasswordEvent) and keyup(confirmPasswordEvent) and not just focus?

Thanks for clarifying

The focus event is only triggered when an element gains focus. This means that if you removed the keyup bit, your confirmPasswordEvent function would only be called when you clicked on the password field.

Adding the keyup event means that the confirmPasswordEvent function is called every time you release a key. This means that it gets called after each character you type, updating the user on whether or not they have met the requirements yet.

Hopefully that helps clarify things, but let me know if you have further questions. Happy coding!
