Hey there,

Hope someone can give me a hand.

That function I have:

```auto
let formattedOutput = [];
let tempArray = [];
let chunkSize = 4; // Each game has 4 elements (time, hometeam, awayteam, channel)

for (let i = 0; i < msg.payload.length; i++) {
    tempArray.push(msg.payload[i]);
    if ((i + 1) % chunkSize === 0) {
        formattedOutput.push(tempArray);
        tempArray = [];
    }
}

let finalOutput = formattedOutput.map(game => {
    return game[0] + " " + game[1] + " VS " + game[2] + " " + game[3];
});

msg.payload = finalOutput.join('\n');
return msg;

```

Outputs a string:

```auto
msg.payload : string[6619]
" 18:45 Portimonense FC Porto SPORT TV1 19:00 Go Ahead Eagles PSV SPORT TV2 19:30 Estugarda Union Berlin ELEVEN SPORTS 2 19:30 SD Huesca FC Andorra ELEVEN SPORTS 5 19:45 Napoli Torino SPORT TV4 20:00 Barcelona Mallorca ELEVEN SPORTS 1 20:00 Nice Montpellier ELEVEN SPORTS 4 20:45 CF Estrela Amadora Casa Pia SPORT TV2 20:45 U. Leiria SAD Oliveirense SPORT TV3 22:00 Caxias São José-RS PFC 11:00 FC Porto S19 Benfica S19 PORTO CANAL 11:00 Mafra Penafiel SPORT TV1 11:00 Sp. Braga FM Lank Vilaverdense FM CANAL 11 11:00 Sporting S17 V. Guimarães S17 SPORTING TV 12:00 Holstein Kiel Karlsruher ELEVEN SPORTS 4 12:00 Schalke 04 SC Paderborn 07 ELEVEN SPORTS 3 12:30 Man Utd Everton ELEVEN SPORTS 1 13:00 Valência Getafe ELEVEN SPORTS 2 14:00 Nacional Ac. Viseu SPORT TV+ 14:30 Bayern München Mainz ELEVEN SPORTS 3 14:30 RB Leipzig SV Darmstadt 98 ELEVEN SPORTS 4 15:00 Torreense FM Sporting FM SPORT TV6 15:00 V. ..."

```

What I want it to do, is to output as arrays; every time there's a format "hh:mm", it creates a new array.

Something like:  
array[1]  
18:45 Portimonense Vs FC Porto SPORT TV1  
array[2]  
19:00 Go Ahead Eagles Vs PSV SPORT TV2  
array[3]  
19:30 Estugarda Vs Union Berlin ELEVEN SPORTS 2  
array[4]  
19:30 SD Huesca Vs FC Andorra ELEVEN SPORTS 5  
array[5]  
19:45 Napoli Vs Torino SPORT TV4  
...

Any ideas?
