Sign up form with Validations JS

Hey guys! This challenge was a bit difficult for me. I have two questions, I would appreciate too much if you help me!

• I used preventDefault(); to disable the submitting if there's an error, but if you fill every field correctly, it is still deactivated. How can I fix that?

• I think email validation is not working very well. if you put [email protected] it's correct, but if you delete any character, it must show an error but isn't work properly. What's the problem there?

Thank you guys, happy coding!
