React components implement a `render()` method that takes input data and returns what to display. This example uses an XML-like syntax called JSX. Input data that is passed into the component can be accessed by `render()` via `this.props`.

**JSX is optional and not required to use React.** Try the [Babel REPL](http://babeljs.io/repl#?babili=false&browsers=&build=&builtIns=false&code_lz=MYGwhgzhAEASCmIQHsCy8pgOb2vAHgC7wB2AJjAErxjCEB0AwsgLYAOyJph0A3gFDRoAJ1Jl4wgBQBKPoKEj4hAK7CS0SfIXQAPGQCWANwB8W7XEQo-hABb6I9NsORsHJMC3gBfM0J0B6AxMzaQBueR8ffmpaQgARAHlUelFyCU0_BCQ0DAhsXHdPAF4AIgAVMABPFGES6H9jABp5FmRlEkIAOWRxfjCgA&debug=false&circleciRepo=&evaluate=false&lineWrap=false&presets=react&targets=&version=6.26.0) to see the raw JavaScript code produced by the JSX compilation step.

Moved home page example code to /content/home Now examples are trasnformed to GraphQL during build and assembled by the index template. This makes them easier to edit and tie in with their associated markdown description. 7 years ago			JSX is optional and not required to use React.
