<p>A JavaScript function block to run against the messages being received by the node.</p>
<p>A JavaScript function block written in <b>Function</b> tab to run against the messages being received by the node.</p>
<p>The messages are passed in as a JavaScript object called <code>msg</code>.</p>
<p>By convention it will have a <code>msg.payload</code> property containing
the body of the message.</p>
<p>The function is expected to return a message object (or multiple message objects), but can choose
to return nothing in order to halt a flow.</p>
<p>Setup code executed before deploy can be specified in <b>Setup</b> tab. Also, cleanup code executed before flow shutdown can be specified in <b>Cleanup</b> tab.</p>
