Return all values inside buffer using arcade

Hello

I have this code which sort values base on buffer 1320 feet and return First values. I want to return all values inside the buffer not just one. is it any way I can do this?

Thanks

// If the feature doesn't have a geometry, return null if (IsEmpty(Geometry($feature))) { return null } // Get the bus stops layer // To customize, replace the layer name below var busStops = FeatureSetByName($map,"RTD Active Bus Stops") // Buffer the current location and intersect with the bus stops var bufferedLocation = Buffer($feature, 1000, 'feet') var candidateStops = Intersects(busStops, bufferedLocation) // Calculate the distance between the bus stops and the current location // Store the feature and distance as a dictionary and push it into an array var featuresWithDistances = [] for (var f in candidateStops) { Push(featuresWithDistances, { 'distance': Distance($feature, f, 'feet'), 'feature': f } ) } // Sort the candidate bus stops by distance using a custom function function sortByDistance(a, b) { return a['distance'] - b['distance'] } var sorted = Sort(featuresWithDistances, sortByDistance) // Get the closest bus stop var closestFeatureWithDistance = First(sorted) // If there was no bus stop, return null if (IsEmpty(closestFeatureWithDistance)) { return null } // Return the bus stop name attribute value // To customize, replace the field name "STOPNAME" below return `${closestFeatureWithDistance['feature']['STOPNAME']}`

To return all the values for the features in the buffer, you have to loop through the sorted FeatureSet and extract the value from each feature. You can add each of the values into an array, then return the concatenated result.

var output= []; for (var f in sorted){ Push(output, f.STOPNAME) } return Concatenate(output,`/n`);
