JSX is not a requirement for using React. Using React without JSX is especially convenient when you don't want to set up compilation in your build environment.
Each JSX element is just syntactic sugar for calling `React.createElement(component, props, ...children)`. So, anything you can do with JSX can also be done with just plain JavaScript.
For example, this code written with JSX:
```js
class Hello extends React.Component {
render() {
return <div>Hello {this.props.toWhat}</div>;
}
}
ReactDOM.render(
<HellotoWhat="World"/>,
document.getElementById('root')
);
```
can be compiled to this code that does not use JSX:
Alternatively, you can refer to community projects such as [`react-hyperscript`](https://github.com/mlmorg/react-hyperscript) and [`hyperscript-helpers`](https://github.com/ohanhi/hyperscript-helpers) which offer a terser syntax.
