let isEmail = someEmail.match(emailRe)

let correctUser = someUser.match(usernameRe)

Credit where credit is due

I wrote this module but NOT the regex, I have found them in various places throughout the internet and saved them in a file for later use, Think it will be easier to store in a module for later.

If you are one of the javascript wizards who wrote one of these expressions please get in touch and I'll either credit you, or remove it from the public module as per your wishes.
