I'm writing a function node that needs to use the node context but on [https://nodered.org/docs/creating-nodes/context](https://nodered.org/docs/creating-nodes/context)  
it shows

```
// Access the node's context object
var context = this.context();

var count = context.get('count') || 0;
count += 1;
context.set('count',count);
//added by me to return the count
msg.payload = context.get('count');
return msg

```

But unless I comment out the 1st line I get an error when I use this example  
#Confused ☹

You are looking at the docs on creating custom nodes. In that case, that first line is required.

The documentation for using Context in the Function node is [here](https://nodered.org/docs/writing-functions#storing-data) and doesn't require that first line as `context` is already defined.

That explains things! 🙂

I just clicked on 1st result instead of the 2nd one
