I get

Uncaught TypeError occurs (Uncaught TypeError: Cannot read property '__SECRET_DOM_DO_NOT_USE_OR_YOU_WILL_BE_FIRED' of undefined)

when I am using React JS

<script src="res/build/react-min.js"></script>
<script src="res/build/react-dom.min.js"></script>
1
javascriptreactjs
But when I use this - <script src="https://fb.me/react-0.14.3.min.js"></script> <script src="https://fb.me/react-dom-0.14.3.min.js"></script>, everything works correctly. Both contain the same scripts. – Kuppuswamy

The error is thrown because the react-dom cannot find an instance of React. I suppose this has something to do with the fact you are using res/build/react-min.js instead of res/build/react.min.js

Kudos for the function name in the react-dom tho:

(function(React) {
  return React.__SECRET_DOM_DO_NOT_USE_OR_YOU_WILL_BE_FIRED;
});
