You could simplify your code in many parts. For instance you code this

```auto
if (!flow.get('tagCounts')) {
    flow.set('tagCounts', {});
}

const tagCounts = flow.get('tagCounts');

```

which could easily be changed to this:

```auto
let tagCounts = flow.get('tagCounts') || {};

```

In 'function 6-delete' you have

```auto
const resetValues = true; // Variable zum Zurücksetzen der Werte

if (resetValues) {
    flow.set('tagCounts', {}); // Setze die Tag-Zählungen zurück
    flow.set('dataArray', []); // Setze das Datenarray zurück
}

msg.payload = []; // Leeres Array für die Table-Node-Daten

return msg;

```

the first two lines are not needed. You could change the code to:

```auto
//reset the flow variables
flow.set('tagCounts', {}); // Setze die Tag-Zählungen zurück
flow.set('dataArray', []); // Setze das Datenarray zurück}

msg.payload = []; // Leeres Array für die Table-Node-Daten
return msg;

```

You should also read up on ['var, let and const'](https://blog.javascripttoday.com/blog/var-vs-let-vs-const/) NOTE: **const** variables can neither be updated nor re-declared.
