Answer 1

You can check if the e-mail address matches your pattern using a regular expression:

var email = input4.toString();

if (/@(gmail|hotmail|outlook|yahoo)\.com$/i.test(email)) {
  // error
} else {
  // success
}

The i behind the expression makes it case insensitive, so that upper-case domains will also be caught.
