Delete multi Layer

[aaronyeo40]

I able to add multi layer based on dynamic url. May I know how to remove layer by id or name (once more than 1 layer).

var url_to_geotiff_fileaaa = "http://localhost:8086/leafletContent/tif/Abc1.tif";

        fetch(url_to_geotiff_fileaaa)
            .then(function (response) { return response.arrayBuffer(); })
            .then(function (arrayBuffer) {
                parseGeoraster(arrayBuffer).then(function (georaster) {
                    layerB = new GeoRasterLayer({
                        georaster: georaster,
                        resolution: 256
                    });
                    layerB.addTo(map);
                    map.fitBounds(layerB.getBounds());
                });
            });
