Remove/delete all markers from map (leaflet)

leaflet.md

I use markercluster

var markers = L.markerClusterGroup()

/* delete method */
map.eachLayer(function(layer) {
    if (layer instanceof L.MarkerClusterGroup)
    {
        map.removeLayer(layer)
    }
})

dataset.forEach(function(item)
{
    var marker = L.marker(item.coordinates, {
        icon: L.divIcon({
            html: `<div><span>1</span></div>`,
            className: 'leaflet-div-icon'
        })
    })

    markers.addLayer(marker)
})

map.addLayer(markers)

There is an easier way: markers.clearLayers()
