  </code></pre>
  
  <p>But when i compile it with <code>ng build --prod</code> it's gives TypeError: $(...).multiple_emails is not a function , if it's not working correctly any other tool to convert from JavaScript to typescript ?   </p>
  
  <p>i had convert js into typesript using online compiler but nothing happened.</p>
