title: How to add polyfill for String.repeat function for ie11?
body: <p>How would I add polyfill for String.repeat method for ie11? I am not using it directly in my code, it's probably some of the imported libs.</p>
  
  <p>In IE console I get this error: <code>Object doesn't support property or method 'repeat'</code></p>
  
  <p>I also get <code>'AbortController' is undefined</code> which I am also not using my code, probably external lib again.</p>
  
  <p>I am using create react app and I imported in index.js:</p>
  
  <pre><code>import 'react-app-polyfill/ie9';
  import 'react-app-polyfill/ie11';
  import 'react-app-polyfill/stable';
  </code></pre>
  
  <p>I tried adding <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/repeat#Polyfill" rel="nofollow noreferrer">https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/repeat#Polyfill</a> to my index.js but it didn't do anything.</p>
  
  <p>Did anyone else have similar problem?</p>
