Adding elements to object

Question

I need to populate a json file, now I have something like this:

{\"element\":{\"id\":10,\"quantity\":1}}

And I need to add another \"elemen

Answer 1

My proposition is to use different data structure that proposed already in other answers - it allows you to make push on card.elements and allow to expand card properties:

let card = {
  elements: [
    {"id":10,"quantity":1}
  ],

  //other card fields like 'owner' or something...
}

card.elements.push({"id":22,"quantity":3})

console.log(card);
