title: React Without JSX

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>;
|
|
}
|
|
}
|
|
|
|
const root = ReactDOM.createRoot(document.getElementById('root'));
|
|
root.render(<Hello toWhat="World" />);
|
|
```
|
|
|
|
can be compiled to this code that does not use JSX:
|
|
|
|
```js
|
|
class Hello extends React.Component {
|
|
render() {
|
|
return React.createElement('div', null, `Hello ${this.props.toWhat}`);
|
|
}
|
|
}
|
|
|
|
const root = ReactDOM.createRoot(document.getElementById('root'));
|
|
root.render(React.createElement(Hello, {toWhat: 'World'}, null));
|
|
```
|
|
|
|
If you're curious to see more examples of how JSX is converted to JavaScript, you can try out [the online Babel compiler](babel://jsx-simple-example).
|
|
|
|
The component can either be provided as a string, as a subclass of `React.Component`, or a plain function.
|
|
|
|
If you get tired of typing `React.createElement` so much, one common pattern is to assign a shorthand:
|
|
|
|
```js
|
|
const e = React.createElement;
|
|
|
|
const root = ReactDOM.createRoot(document.getElementById('root'));
|
|
root.render(e('div', null, 'Hello World'));
|
|
```
|
|
|
|
If you use this shorthand form for `React.createElement`, it can be almost as convenient to use React without 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.
