<p>A function block where you can write code to do more interesting things.</p>
<p>The message is 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 should return the messages it wants to pass on to the next nodes
in the flow. It can return:</p>
<ul>
<li>a single message object - passed to nodes connected to the first output</li>
<li>an array of message objects - passed to nodes connected to the corresponding outputs</li>
</ul>
<p>If any element of the array is itself an array of messages, multiple
messages are sent to the corresponding output.</p>
<p>If null is returned, either by itself or as an element of the array, no
message is passed on.</p>
<p>See the <a target="_new" href="http://nodered.org/docs/writing-functions.html">online documentation</a> for more help.</p>
