I want to reduce the array loop. If you leave it like that it will be very slow.

const filteredBudgetItems = [{
    name:A,
    age:2,
    budgetItemId:47,
    bugdetData:{
      id:87,
      name:ul
    }
  }, //..10000 pieces object
]

const rowIndex = //always different numbers
const activeRows = [//always different numbers] // array

const el = useMemo(() => filteredBudgetItems?.[rowIndex], [filteredBudgetItems, rowIndex])
const getIsActive = useCallback((rowPosition) => !!activeRows.find((el) => el === rowPosition), [activeRows]);
const isActive = useMemo(() => getIsActive(el?.budgetItemId), [el, getIsActive]);
