Answer 1

UPDATE -- use this instead:

<script type="text/babel" src="./lander.js"></script>

Add type="text/jsx" as an attribute of the script tag used to include the JavaScript file that must be transformed by JSX Transformer, like that:

<script type="text/jsx" src="./lander.js"></script>

Then you can use MAMP or some other service to host the page on localhost so that all of the inclusions work, as discussed here.

Thanks for all the help everyone!

If you have something like

Uncaught SyntaxError: embedded: Unexpected token

You probably missed a comma in a place like this:

  var CommentForm = React.createClass({
  getInitialState: function() {
      return {author: '', text: ''};

  }, // <---- DON'T FORGET THE COMMA

  render: function() {
      return (
      <form className="commentForm">
          <input type="text" placeholder="Nombre" />
          <input type="text" placeholder="Qué opina" />
          <input type="submit" value="Publicar" />
      </form>
      )
  }
  });
