 **JSX lets you write JavaScript function calls with HTML syntax.** To generate a link in React using pure JavaScript you'd write: `React.DOM.a({href: 'http://facebook.github.io/react/'}, 'Hello React!')`. With JSX this becomes `<a href="http://facebook.github.io/react/">Hello React!</a>`.

 The easiest way to get started with JSX is to use the in-browser `JSXTransformer`. We strongly recommend that you don't use this in production. You can precompile your code using our command-line [react-tools](http://npmjs.org/package/react-tools) package.
