'Remove data undefined in popup map Javascript

I have json data, and the data is displayed in a pop up on a map when there is a data that does not exist (Visibility), then the word undefined appears on the pop up

How to remove undefined text, so that it gets deleted on the pop up?

json data :

[{
"date":"03-03-2022",
"lat":-5.67,
"lng":80.65,
"weather":"2",
"temperature": "24.4",
"Humidity": "90",
"Wind": "100"}]

script js :

<script>
for (i = 0; i < dataJSON.length; i++) {
    var weather = parseInt(dataJSON[i].weather)
    var Coordinate = new L.latLng(([dataJSON[i].lat, dataJSON[i].lng]))
    var marker = L.marker(Coordinate, { icon: customIcon })
    marker.bindPopup('Date : ' + dataJSON[i].date + 'Temperature : ' + dataJSON[i].temperature + 'RH :' + dataJSON[i].Humidity
        + 'wind :' + dataJSON[i].Wind + 'Visibility :' + dataJSON[i].Vis
    )
}

Pop Up :
