React - Load Initial List via AJAX

I'm starting to learn react. There's an excellent example in the official docs about loading data initially via AJAX:

var UserGist = React.createClass({
getInitialState: function() {
return {
username: '',
lastGistUrl: ''
};
},

componentDidMount: function() {
this.serverRequest = $.get(this.props.source, function (result) {
var lastGist = result[0];
this.setState({
username: lastGist.owner.login,
lastGistUrl: lastGist.html_url
});
}.bind(this));
},

componentWillUnmount: function() {
this.serverRequest.abort();
},

render: function() {
return (
<div>
{this.state.username}'s last gist is
<a href={this.state.lastGistUrl}>here</a>.
</div>
);
}
});

ReactDOM.render(
<UserGist source="https://api.github.com/users/octocat/gists" />,
mountNode
);


The code above gets the latest gist of a specific user from GitHub.

What is the best way in React to go about outputting a list of the last 10 gists of the specific user?

How would you modify the code sample above?

Answer
var UserGist = React.createClass({
    getInitialState: function() {
        return {
            gists: []
        };
    },

    componentDidMount: function() {
        this.serverRequest = $.get(this.props.source, function (result) {
            this.setState({
                gists: result
            });
       }.bind(this));
    },

    componentWillUnmount: function() {
        this.serverRequest.abort();
    },

    render: function() {
        return <div>
            {this.state.gists.map(function(gist){
                return <div key={gist.id}>{gist.owner.login}</div>
            })}
        <div>;
    }
});

ReactDOM.render(
    <UserGist source="https://api.github.com/users/octocat/gists" />,
    mountNode
);
