Javascript in n8n: combine 2 JSON arrays into one structure

In a project I pull JSON-objects out of the Zammad-API.

I get the ticket:

A freelancer has written a piece of nodejs that I can call via http-request.

That code needs both JSON-objects combined in one "body", like in:

In my n8n-workflow I can add js-code to do that, could someone help me writing this?
I googled around merging and concatenating json, but the additional adding of the "names" makes it harder for me (adding "Ticket:" and "articles:" ...). I am not a js-coder at all ... so far

Any help appreciated! thanks

Assuming you have your tickets stored in some variable named tickets and all your articles stored in some variable named articles. You can simply map your tickets to your new combined type as such.

let cominedTickes = tickets.map(ticket => ({
Ticket: ticket,
articles: articles.filter(article => article.ticket_id === ticket.id)
}));

You can simply filter the articles for each ticket by the ticket_id.
