How to update the props property of type array after filtering in one functionnal component

React js

Hello I need to filter props.arrayData with filtering in one functionnal component

export function BurnSegments({ arrayData }) { function handleChange(event) { event.preventDefault(); this.setState({ arrayData : arrayData .filter(b => b.key === }); }


But setState is undefined, so what is the proper way of changing arrayData in the props?

I made it work by using the useState of the functional component as we can't update props.

with the steps:


  • create a State with useState in the functional component called statearrayData (to distinct it from the props called arrayData)
  • in the useEffect : update the state with the props arrayData by using setStatearrayData ==> triggered on the first render and when redux state is updated
  • in the handleChange we also use setStatearrayData ==> we can filter the props and update the component state

By the way I used redux here

export function Sample({ arrayData}) { const [statearrayData , setStatearrayData ] = useState([]); useEffect(() => { // we update here the state with the prop setStatearrayData (arrayData); }, [arrayData]); function handleChange(event) { event.preventDefault();setStatearrayData(arrayData.filter(b => b.key ===; }}function mapStateToProps(state) { return { arrayData: state.arrayData };}function mapDispatchToProps(dispatch) { ....}export default connect(mapStateToProps, mapDispatchToProps)(Sample);
