const fiftyFifty = Math.random() < 0.5;

// New component class starts here:
class TonightsPlan extends React.Component{
  render(){
    if (fiftyFifty) {
     return <h1>Tonight I'm going out WOOO</h1>; //place return inside each condition
    }
    else {
      return <h1>Tonight I'm going to bed WOOO</h1>;
    }
  }

ReactDOM.render(<TonightsPlan />, document.getElementById('app'));
