title: Understanding refs in react native
body: <p>So i am learning about refs (in react native). On react site <a href="https://reactjs.org/docs/refs-and-the-dom.html" rel="nofollow noreferrer">here</a>, it says that;</p>
  <blockquote>
  <p>For example, instead of exposing open() and close() methods on a Dialog component, pass an isOpen prop to it.</p>
  </blockquote>
  <p>Thus, not recommending using refs too much.</p>
  <p>Please explain why?</p>
  <p>What is the down point of using refs and why reactjs.org says so.</p>
