## JSFiddle
The easiest way to start hacking on React is using the following JSFiddle Hello World examples:
* **[React JSFiddle](http://jsfiddle.net/vjeux/kb3gN/)**
* [React JSFiddle without JSX](http://jsfiddle.net/vjeux/VkebS/)
## Starter Kit
Download the starter kit to get started.
In the root directory of the starter kit, create a `helloworld.html` with the following contents.
```html
```
The XML syntax inside of JavaScript is called JSX; check out the [JSX syntax](/react/docs/jsx-in-depth.html) to learn more about it. In order to translate it to vanilla JavaScript we use `
```
### Offline Transform
First install the command-line tools (requires [npm](http://npmjs.org/)):
```
npm install -g react-tools
```
Then, translate your `src/helloworld.js` file to plain JavaScript:
```
jsx --watch src/ build/
```
The file `build/helloworld.js` is autogenerated whenever you make a change.
```javascript{2}
React.renderComponent(
React.DOM.h1(null, 'Hello, world!'),
document.getElementById('example')
);
```
Update your HTML file as below:
```html{6,10}
Hello React!
```
## Want CommonJS?
If you want to use React with [browserify](http://browserify.org/), [webpack](http://webpack.github.io/), or another CommonJS-compatible module system, just use the [`react` npm package](https://www.npmjs.org/package/react). In addition, the `jsx` build tool can be integrated into most packaging systems (not just CommonJS) quite easily.
