Delete Cluster Layers

[LIZDean]

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.

Thanks @Sage_Wall I will give them a go 🙂
