Intro component with sign-up form validation using JavaScript & HTML

Working with this challenge, I have learned how to create a basic form validation system using JavaScript, HTML, and CSS.

I used regular expressions to validate email addresses and display specific error messages.

const emailRegex = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+.[a-zA-Z]{2,}$/;

What other ways to validate email that covers many test cases? I am open to any alternative solution for email validation, thank you!
