Form validation is crucial for ensuring that user-submitted data meets the required criteria. In this guide, we'll explore how to perform form validation for email and password fields using JavaScript and provide examples to illustrate their usage.

Validation Rules

We've applied the following validation rules:

  • Email: Must be a valid email address.
  • Password: Must contain at least 8 characters, including one uppercase letter, one lowercase letter, and one digit.


Form validation is essential for ensuring that the data submitted by users is accurate and secure. By implementing validation rules for fields like email and password, you can enhance the user experience and protect your application from invalid or malicious data.
