How can I add support for a + (plus sign) in this email validation regex?

Question

This is a regular expression I found online that seems to do a great job at simple email address validation. The problem is it doesn't allow + in the email, like my+email@domain.com. I'm not great at regex, so how can I add support for a + without breaking the whole thing?

var regex = new RegExp( /^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i );

Answer 1

([+\w0-9._-]+@[\w0-9._-]+\.[\w0-9_-]+)

Answer 2

Change the second [\w-]+ to [+\w-]+
