You can just iterate over the array.

Example:

categoryArray.forEach(val => console.log(val.id));

In your case you have multiple ids, so you have to iterate through the array and you can print all ids. You can use map do achieve that:

res.data.map(el => console.log(el.id));

To get all the ids as you want:

const allIds = res.data.map(el => { return {id: el.id} })
