title: What are the options in create-react-app for dealing with rest-syntax issues in Edge?
body: <p>I have a react app based on <code>create-react-app</code> that makes much use of object rest/spread syntax as defined <a href="https://github.com/tc39/proposal-object-rest-spread" rel="nofollow noreferrer">here</a>. This works fine in Chrome and Firefox, but crashes Edge &lt; 79.</p>
  
  <p>I have tried adding the <code>react-app-polyfill</code> and <code>core-js</code> imports, as recommended in the docs. These fix a few other issues, but don't touch this syntax problem.</p>
  
  <p>Examples of the problem code:</p>
  
  <pre><code>const { x, y, ...rest} = props;
  const newprops = {...rest, z:1 }
  </code></pre>
  
  <p>Is there any way of handling this without ejecting the project?</p>
