is there a way to bind multiple properties in a popup with leaflet?

I'm loading in a JSON file that looks like this:

As you can see, there are several properties.
I'm currently using this code

L.geoJson(jsonObject, {
onEachFeature: function (feature, layer) {
layer.bindPopup(feature.properties.name);
}
}).addTo(map);


Is there a way to bind >1 propertie to the popup?

Answer

Use + to concatenate Strings in JavaScript.

E.g. feature.properties.name + " " + feature.properties.venue_type + ...
