My redux prop gives me empty data after access it from flatList onRefresh

Question

If I call my reload method for the first time via useEffect it contains my data, but if I called via onRefresh at runtime, it gives me empty data.

Why? How should I save that? Is it a problem on which thread onRefresh is called?

For more information about my item please look to this question, maybe it is the same issue.

const MyScreen = ({ items }) => {
    const [initialItems, setInitialItems] = useState(items)
   
    useEffect(() => {
        reload()
    }, [])

    const reload = () => {
        console.log(initialItems) // same value 
        console.log(items) // same value 
    }


    return (
        <FlatList
            ...
            refreshControl={
                <RefreshControl
                refreshing={isRefreshing}
                onRefresh={() => reload()} 
                />
            }
            ...
        />
    )
}

const mapStateToProps = (state) => { 
    return {
        items: state.items, // I tried this also with [...state.items]
    }
}

Answer 1

My mistake was copying my Array like that: xArray = yArra it means call by reference and not by value.
