  <p>while trying to use React-data-grid. The issue is on the server side while trying to build the nodejs application using webpack. We are facing issue in the generated bundle file in the following lines</p>
  
  <pre><code>isOldIE = memoize(function() {          return /msie
  [6-9]\b/.test(self.navigator.userAgent.toLowerCase());      }),
  </code></pre>
  
  <p>Could you let us know how can we fix this. It looks like the react data grid package has issues with the server side rendering.</p>
