Adding a comma between multiple values

IanLadd_Tourmaline

Hello,

I have an Arcade script that inserts the name of a boundary polygon if it intersects with the feature. How do I show a comma between only the ones where it intersects multiple polygons? My current code just adds a "," to everyone regardless if it's only one value.

 

var land = FeatureSetByName($datastore,"Boundary_Aug2024",["Name"], true)
var intersectLayer = Intersects(land, Geometry($feature))
var result = '';
if (Count(intersectLayer) > 0) {
    for (var layer in intersectLayer) {
        result += layer.Name+(", ") ;
    }
} else {
    result = "Null"
}  
return result

You can add the items to an array and use the Concatenate function. This wouldn't add an extra comma if there is only one result.

var land = FeatureSetByName($datastore, "Boundary_Aug2024", ["Name"], true);
var intersectLayer = Intersects(land, Geometry($feature));
var result = [];
if (Count(intersectLayer) == 0) return "Null";
for (var layer in intersectLayer) {
  Push(result, layer.Name);
}
return Concatenate(result, ", ");
