  • Beside that you have two `@`, should think about just using something like `/^\S+@\S+$/`. Your RegExp does not accept many valid email addresses. E.g. `someone@example.email` or `some+info@example.com` and all those international domains that have to be encoded as punycode. – t.niese Sep 21 '17 at 13:35

two ampersand symbols is the problem. 

var reg = /^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/;

  • "[" is not valid at the start of a code block. Only identifiers, keywords, comments, "(" and "{" are valid. – Ivin Raj Sep 21 '17 at 13:30
