Good morning,

I have a message like this:

```auto
{
   "dataflow":[
      {
         "date":"Dec 17, 2020 7:20 AM",
         "id":2,
         "cod":27,
         "value":676
      },
      {
         "date":"Dec 17, 2020 7:22 AM",
         "id":2,
         "cod":28,
         "value":670
      },
      {
         "date":"Dec 17, 2020 7:25 AM",
         "id":2,
         "cod":25,
         "value":717
      }
	]
}

```

I would retrieve and send data if cod==25 (example) with a function node or other node.  
How can I do?  
Thank you very much 🙂

Use [array find](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find) in a function

E.g...

```auto
msg.payload = msg.dataflow.find(e=>e.id==25);
return msg;

```

You could also replace the 25 with another msg property e.g.

```auto
msg.payload = msg.dataflow.find(e=>e.id==msg.find);
return msg;

```
