I'n trying to separate one flow depending if one property is included in a set of values or in other. By now it only has two options (two different sets) but today may have more.  
I'm trying to acomplish this in a function node. I would prefer it in a split module for optimization, but still don't have the skills.  
Anyways none of the JS methods I know work there. This is the function:

```auto
const sensors = [1,4,5,6,7,8,9,10,11];
const actuators = [2,3];

//if (sensors.includes({msg.subType})){ // Doesn't work.
if ($.inArray({msg.subType},sensors) > -1) // Also doesn't work
    return msg, null;
else if ($.inArray({msg.subType},actuators) > -1) // Also doesn't work
    return null, msg;
    
return null,null;

```

I would thank some help from a more experienced node-red user.

Show us the actual data. Put a debug node on the output of what ever is feeding your function node and change the debug node to display the complete msg object

That is a jQuery function that isn't needed in modern javascript. Nor is it available in the node.js runtime environment.

Assuming you want to check if the value of `msg.subType` appears in the `sensors` and `actuators` arrays, you can do:

```auto
const sensors = [1,4,5,6,7,8,9,10,11];
const actuators = [2,3];

if (sensors.indexOf(msg.subType) > -1)
    return [msg, null];
else if (actuators.indexOf(msg.subType) > -1)
    return [null, msg];

return;

```

For reference, see [MDN's docs on Array.indexof](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/indexOf).

That's it! Thanks @knolleary.  
Do you think it would be possible by only using switch nodes?
