is anybody experienced the same way?

```auto
useEffect (() => {
        setNoItems(count);
        setTitlex(title);
        if(operator==1 || operator==0){
            setMinusx(operator);
            setChecking(0);
        }
        if(operator==2 || operator==0){
            setPlusx(operator);
            setChecking(0);
        }
        setSelectedItem(checking);
        //all sets are props
        console.log("check "+checking);
    });//issue about this is that the last component in array cause a React app freeze

```

```auto
useEffect (() => {
        setNoItems(count);
        setTitlex(title);
        if(operator==1 || operator==0){
            setMinusx(operator);
            setChecking(0);
        }
        if(operator==2 || operator==0){
            setPlusx(operator);
            setChecking(0);
        }
        setSelectedItem(checking);
        //all sets are props
        console.log("check "+checking);
    },[count,operator,checking]);//this time I add dependency, issue about this is that the moment I click the component React app freeze

```

Any help would be appreciated! I am a newbie in hooks

According to [this SO answer](https://stackoverflow.com/questions/53715465/can-i-set-state-inside-a-useeffect-hook#answer-54923969) “using `setState` inside `useEffect` will create an infinite loop that most likely you don’t want to cause.”

thanks for your answer sir. Can you suggest on how can I pass that value inside the useEffect to other screen. Since I’m trying to pass all the data from my component to CartScreen and vise versa.

Instead of using `useEffect`, can you pass the the data via props? Maybe something like what’s described in [this SO article](https://stackoverflow.com/questions/53942539/how-to-pass-data-between-react-native-screens)?
