 If you're curious to see more examples of how JSX is converted to JavaScript, you can try out [the online Babel compiler](https://babeljs.io/repl/#?babili=false&evaluate=true&lineWrap=false&presets=es2015%2Creact%2Cstage-0&code=function%20hello()%20%7B%0A%20%20return%20%3Cdiv%3EHello%20world!%3C%2Fdiv%3E%3B%0A%7D).

 ```js
 var e = React.createElement;
 
-ReactDOM.render(e('div', null, 'Hello World'),

+ReactDOM.render(
