// The solution below is optimal because it uses a regular expression to validate the email.
// The regular expression is a pattern that is used to match the email.
// The regular expression is tested against the email to see if it matches.
// If it matches, the email is valid.

function validateEmail(email) {
  var re = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
  return re.test(String(email).toLowerCase());
}

// Example:

validateEmail("test@test.com"); // true
validateEmail("test@test"); // false
