Hello everyone,

Im using Function node a lot.

But I am seeing irratic behaviour of node red. Atleast thats how I percieve it. Might be due to a lack of understading 🙂

```auto
var nr_corr = global.get('NightReduction_current_value',"file");
msg.payload = nr_corr;
return msg;

```

Debug node after and inject node in front shows this produces value 0. As expected. It is also the stored value.

If I want to have a default value of 10 when the variable is undefined, I was thinking that adding "||10 " would be enough. like below

```auto
var nr_corr = global.get('NightReduction_current_value',"file")||10;
msg.payload = nr_corr;
return msg;

```

I expect it to produce 0 now. Because the value is known as shown in the first example.  
But the debug node shows value 10 instead.

Is there something I am missing?  
This behaviour is sometimes there, sometimes not.

Im currently using NodeRed version 3.0.2

many thanks in advance 😄
