title: is It possible to develop common business logic that run in both android and iOS platform?
body: <p>I have <code>iOS</code> and <code>android</code> application already developed. I just want to add offline support on both platforms but I want to write business logic at once for both platform weather it will be written in <code>NodeJs</code>, <code>Js</code> or any other language that communicates with the local database as well. </p>
  
  <p>Is that possible to implement such functionality? if possible then how? which language is most preferable for such situation?</p>
