Comment (by nerrad):

 @CantoThemes what may be happening in your case is `react` and `react-dom`
 are being printed AFTER your script requiring them.  What you need to do
 is register 'react' and 'react-dom' as dependencies on your script and
 then just enqueue your script in `load_assets`.

 So something like:

 {{{
 wp_register_script( 'my-script-handle', $my_script_location, array(
 'react', 'react-dom' ), $version, $in_footer );
 }}}

 Then in your `load_scripts` callback just call `wp_enqueue_script( 'my-
 script-handle' )`.

 This will ensure that your script is printed AFTER react and react-dom on
 the page.
