Delete Cluster Layers

Question

I have some Javascript code that creates three cluster layers.

I need to be able to clear the three layers (workLayer, educationLayer, volunteerLayer) when I start a new process but can't figure out the right function.

This is what I have but it leaves the layers / graphics there.

function clearLayers() {                [workLayer, educationLayer, volunteerLayer].forEach(layer => {                    if (layer.source) {                                                layer.source.remove()                                                                   }                });            }

Hi @LIZDean

* FeatureLayer.applyEdits() - if you want to delete the features but leave the layers for later use
* Map.removeMany() - if you want to remove the layer from the map but maybe readd it again
* FeatureLayer.destroy() - if you want to destroy the reference to the layer and free up the memory. The layer and any associated resources no longer exist.
