## Full example

    var ExampleApplication = React.createClass({
        render: function() {
          var elapsed = Math.round(this.props.elapsed  / 100);
          var seconds = elapsed / 10 + (elapsed % 10 ? '' : '.0' );
          var message =
            'React has been successfully running for ' + seconds + ' seconds.';

          return <p>{message}</p>;
        }
      });
      var start = new Date().getTime();
      setInterval(function() {
        React.render(
          <ExampleApplication elapsed={new Date().getTime() - start} />,
          document.getElementById('container')
        );
      }, 50);
