JavaScript Regular Expressions in JavaScript Validating a Form Validating an Email

Regex related to user input security concerns?

I love this JS regex course and feel like I am learning a lot.

With regards to the actual validation of emails and other user info, I was wondering if we should be concerned about the info that the user is supplying beyond the regex.

Should there be anything on the front end that we should use to help avoid any malicious users to enter things that they shouldn't with our forms?

(I have been through some of the Treehouse security courses, so it has me starting to think about these things.)

I'd love any more info and/or actionable steps. :)

I'm no expert, but I think we do what we can on the frontend but know that the backend is where we have to be careful since it isn't hard to bypass most frontend validation. I see what looks like a course for you.
