title: React es6 es2015 modal popup
body: <p>I'm very new to React and ES6. I'm building a small application using React and I'm following ES6 standard. Now I need to open a modal window on a button click. </p>
  
  <p>I tried react-bootstrap modal and skylight. But did not find much luck.</p>
  
  <p>Can anyone suggest the best way of opening/closing modal along with a callback.</p>
  
  <p>Thanks in advance.</p>
