```javascript
return React.createElement('div', {className: 'shopping-list'},
React.createElement('h1', ...),
React.createElement('ul', ...)
React.createElement('h1', /* ... h1 children ... */),
React.createElement('ul', /* ... ul children ... */)
);
```

If you're curious, `createElement()` is described in more detail in the [API reference](/react/docs/react-api.html#createelement), but we won't be using it directly in this tutorial. Instead, we will keep using JSX.

You can put any JavaScript expression within braces inside JSX. Each React element is a real JavaScript object that you can store in a variable or pass around your program.

The `ShoppingList` component only renders built-in DOM components, but you can compose custom React components just as easily, by writing `<ShoppingList />`. Each component is encapsulated so it can operate independently, which allows you to build complex UIs out of simple components.
