Hi,

I try to create function which filters data out based on values.

 ![Screenshot 2021-02-16 at 17.22.43](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/8/5/8507c94cf459748f734110fdaa65a27b419dd992.png)

I only need values where visible is true. I've been banging my head against wall now 2 days for this.  
If there is better way to do this than function, it would be nice to hear it.

Thank you very much, for help.

Br,

Ville

Assuming that this array of objects is in `msg.payload` then a simple Javascript function would work:

```auto
msg.payload = msg.payload.filter(o => o.visible);
return msg;

```

Since you said you don't want to use the `function` node, I would tend to use a `change` node with this JSONata expression:

```auto
payload[visible=true]

```

Actually, I was surprised to see that there is no built-in core node called `filter` or some such thing... I thought there was one. Did I just miss it?

Try using change node and JSONata

```auto
payload[visible=true]

```

[edit] i see @shrickus already suggested it.
