This allows you to render tab items conditonally since the false condition returns null in that case.

This allows the following constructs:

  return (
    <TabNavigator>
      // Other TabNavigator.Item

      {(() => {
        if (debug) {
          return (
            <TabNavigator.Item title="Debug">
              <Debug navigator={navigator}/>
            </TabNavigator.Item>
          )
        }
      })()}
    </TabNavigator>
  )
