Answer 1

You can use filter() function to achieve this. You can read the docs here.

const state1 = [];
const state2 = [];

const itemsWithIdRtFromState1 = state1.filter(item1 => {
    return state2.filter(item2 => item2?.id_rt === item1?.id_rt)
});

const itemsWithIdRtFromState2 = state2.filter(item2 => {
    return state1.filter(item1 => item1?.id_rt === item2?.id_rt)
});
