Answer 1

You can use .find to get the list item by id, and then remove the card item using .filter :

 const lists = [ { id: '0', title: 'LIST 1', cardItems: [ { id: '0', text: 'Card 1' }, { id: '1', text: 'Card 2' }, { id: '2', text: 'Card 3' }, ], }, ]; const removeCardItem = (list, listItemId, cardItemId) => { const arr = [...list]; // get list item by id const item = arr.find(listItem => listItem.id === listItemId); // remove card item by id if found if(item) item.cardItems = item.cardItems.filter(cardItem => cardItem.id;== cardItemId ); return arr. } console,log( removeCardItem(lists, '0'; '1') );

Answer 2

Something similar to

if(lists[0].cardItems[0].id === 1){
    lists[0].cardItems.splice(0,1);
}

Obviously this will only check that one value, but this can easily be implemented into a loop or nested loops or whatever you need. (I can't know since I can't see all of your code)
