how to use multiple latitude and longitude in Marker(React native MapView)-CodePudding

I have more than 10 latitude and longitude, I want to display them in Marker. How can i show them in marker for react native mapView. Already I have tried to do a function an call the function in return which is not giving anything in map. anyone can help me if I have done anything wrong or how to fix this and i can show my latitude and longitude in Marker.

To call latitude and longitude I used for loop to get all the latitude and longitude.

Please help me to display all the location (latitude & longitude) in Marker. ThankYou for your Trying in advance!

   function markers() {
        for (let i = 0; i < vp?.length; i  ) {
            for (let j = 0; j < vp[i]?.length; j  ) {
                let longitude = vp[i][0];
                let latitude = vp[i][1];
                <Marker
                    coordinate={{
                        longitude: longitude,
                        latitude: latitude,
                    }}
                ></Marker>
            }
        }
    }
    return (
        <View style={styles.container}>
            <MapView
                style={styles.map}
                initialRegion={{
                    longitude: 113.3661,
                    latitude: 4.7631,
                    latitudeDelta: 0.0922,
                    longitudeDelta: 0.0421,
                }}>
                {markers}              
            </MapView>
        </View>
    );

You can simply do this with a map like this simpler and with less code. You forgot to return the marker component.

  return (
        <View style={styles.container}>
            <MapView
                style={styles.map}
                initialRegion={{
                    longitude: 113.3661,
                    latitude: 4.7631,
                    latitudeDelta: 0.0922,
                    longitudeDelta: 0.0421,
                }}>
                // change your code here
                {vp.map((m)=><Marker
                    coordinate={{
                        longitude: m[0],
                        latitude: m[1],
                    }}
                ></Marker>)}              
            </MapView>
        </View>
    );
