Tests:

immer
data = produce(INITIAL_DATA, draft => { draft.items[NEW_ITEM_ID] = { id: NEW_ITEM_ID, name: 'ITEM-NEW', value: 0 } draft.count++ draft.keys.push(NEW_ITEM_ID) })
shallow copy
data = { ...INITIAL_DATA, items: { ...INITIAL_DATA.items, [NEW_ITEM_ID]: { id: NEW_ITEM_ID, name: 'ITEM-NEW', value: 0 } }, count: INITIAL_DATA.count +1, keys: [ ...INITIAL_DATA.keys, NEW_ITEM_ID] }
ramda evolve
data = evolve({ items: assoc(NEW_ITEM_ID, {id: NEW_ITEM_ID, name: "ITEM-NEW", value: 0}), count: x => x + 1, keys: append(NEW_ITEM_ID) }, INITIAL_DATA);
