Just use Array#map

const arr = [{id: 1, url: 'something'},{id: 2, url: 'something2'}];
const mapped = arr.map(({id}) => ({ id }));

console.log(mapped);

In simple form

const arr = [{id: 1, url: 'something'},{id: 2, url: 'something2'}];
const mapped = arr.map(item => { return { id: item.id };});

console.log(mapped);
