es6: How to define functions inside a const?
<p>I'm doing this react-native project and i am using <a href="https://medium.com/the-react-native-log/organizing-a-react-native-project-9514dfadaa0#.u7ggwk3uq" rel="noreferrer">this method</a> to organize my project files but i don't know how to declare functions inside a const.</p>

<pre><code>import React from 'react';
import { View, ListView, Text } from 'react-native';

const Category = (props) =&gt; {

    const ds = ListView.DataSource({rowHasChanged : (r1, r2) =&gt; r1 !== r2});

    // how to declare function here?

    return (
        &lt;View&gt;
            &lt;ListView
                dataSource={ds}
                renderRow={(rowData) =&gt; &lt;Text&gt;{rowData}&lt;/Text&gt;}
                renderSeparator={// how to put function reference here?}
            /&gt;
        &lt;/View&gt;
    );
}
</code></pre>
