    Aim:

    The aim of this experiment is to validate the registration, user login, user profile, and payment by credit card pages
    using JavaScript. By implementing validation, we can ensure that the input provided by users is correct and meets the
    required criteria. This will enhance the user experience and prevent potential issues with data integrity.

    Algorithm:

    Registration Page Validation:

    1. Validate that all required fields are filled in before submitting the form.

    2. Check the validity of email addresses entered by users.

    3. Ensure that passwords meet the required complexity criteria (e.g., minimum length, containing both letters and
    numbers).

    4. Verify that password and confirm password fields match.

    5. Optionally, perform additional validation specific to your application's requirements (e.g., username
    uniqueness).

    User Login Validation:

    1. Validate that both the username/email and password fields are filled in before allowing login.

    2. Verify the entered credentials against the stored user database.

    3. Optionally, implement additional security measures like rate limiting or CAPTCHA to prevent brute-force
    attacks.

    User Profile Validation:


    1. Validate any required fields specific to the user profile page.

    2. Implement additional validation for fields like phone numbers, addresses, or other user-specific information.

    3. Ensure any changes made to the profile are correctly saved and updated in the database.

    Payment by Credit Card Validation:

    1. Validate the credit card number format (e.g., using regex) to ensure it matches a valid credit card pattern.

    2. Implement the Luhn algorithm to validate the credit card number's checksum.

    3. Verify the expiration date and CVV number against their respective criteria.

    4. Optionally, integrate with a payment gateway to perform real-time validation or verification.
