1.The 'validateCredentials' function checks whether the provided username and password are valid. This makes the code more modular and allows for easier changes to the validation logic. 2.The 'redirectToPage' function abstracts the logic for redirecting to a specific page. This can be useful if you need to change the redirection logic in the future. 3.The 'showLoginError' function encapsulates the logic for displaying the login error message. It makes the code more self-explanatory.
