Right:

if (true) {
  var email = '[email protected]';
  var regex = /^([a-zA-Z0-9_.+-])+\@(([a-zA-Z0-9-])+\.)+([a-zA-Z0-9]{2,4})+$/;
  var isEmail = regex.test(email);
}

Wrong:

if (true) {
  var email = '[email protected]';
  var isEmail = /^([a-zA-Z0-9_.+-])+\@(([a-zA-Z0-9-])+\.)+([a-zA-Z0-9]{2,4})+$/.test(email);
}
