ViewBag is rendered and execute in the server side, react is invoked on the browser (client).
Your main options are:

1. Global variable - In the razor (.cshtml) you can set a global object window.param = ViewBag.param. and access it from react.
   const x = window.param

2. Pass a value (primitives only) to the root element of react via a data-attribute and grab it before you call render: example:

       // razor (.cshtml)
           <div id="root" data-param="@ViewBag.param"></div>
   
      // react
           const root = document.getElementById('root');    
           const param =  root.getAttribute('data-param');
           render(<App myParam={param}/>, root)
