var contacts = [{ id: "1", name: "test" }, { id: "2", name: "foo" }, { id: "3", name: "june" }, { id: "4", name: "may" }],
    filtered_contacts = [{ id: "1", options: [{ option_id: "1", contact_linked_id: "2" }, { option_id: "2", contact_linked_id: "4" }] }, { id: "2", options: [{ option_id: "3", contact_linked_id: "1" }] }],
    cSet = filtered_contacts.reduce(
        (s, { options }) => options.reduce(
            (t, { contact_linked_id: id }) => t.add(id),
            s
        ),
        new Set
    ),
    result = contacts.filter(({ id }) => cSet.has(id));
