    Validate an email in JavaScript using regular expression.

    Remember that JavaScript might be disabled in your browser and that server-side validation is always required.

    Shortcut: email.isvalid

    const isValid = String(email)
      .toLowerCase()
      .match(
      /^(([^<>()[\]\\.,;:\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,}))$/
    );
