I have 2 different arrays, that i want to combine. The first one looks like following:
const Cats[] = [
{ id: '1', name: 'Smiley' },
{ id: '2', name: 'Purple' },
]
the second one:
const catAges[] = [
{ id: '4', age: '13', catId: '1' },
{ id: '5', age: '4', catId: '2' },
];
and i want to combine them where id
from Cats[]
and catId
from catAges[]
are the same and have a result like following:
{ id: '4', age: '13', cat: { id: '1', name: 'Smiley' } },
{ id: '5', age: '4', cat: { id: '2', name: 'Purple' } },
i get the arrays from 2 different async functions looking like this:
const cats = [await getByCatId("1"), await getByCatId("2")];
const catsAge = await getCatsAges();
But i need help in how i combine these 2 and map them. I've tried something like this but without any success:
const all = (cats, catsAge) =>
cats.map(cats=> ({
...catsAge.find((cats) => (catsAge.catId === cats.id) && catsAge),
...cats
}));
console.log(all(cats, catsAge));
Thankful for any help in how to move forward.
