how can i make a regular expression to validate an email? using while

Answer 1

^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$

Answer 2

we generally use a simpler regex for simple client side validation for emails, as shared by Calviղ.

But in reality the true regex for email validation is super big, long ago I tried to do it, I ended up being depressed :-(

I ll give it a try again today, Here's the code if you are interested, with valid and invalid test cases
