I am using Mapbox gl js to update my map dynamically. I am able to add new markers. How do I remove all markers on the map? I've tried using this MapBox clear all current markers but I'm not storing the markers anywhere to keep track of them. I see this solution MapBox GeoJSON clear all markers? but I am not using leaflet. any idea?

map.on('load',function(){



    window.setInterval(function(){



    $.getJSON('some url', function(geojson) {

        geojson.features.forEach(function(marker) {



        var el = document.createElement('div');



        el.style.backgroundImage = 'url(https://placekitten.com/g/50/)';              

        el.style.width = '50px';                                                      

        el.style.height = '50px';

        el.style.borderRadius = '50%';



        new mapboxgl.Marker(el)

            .setLngLat(marker.geometry.coordinates)

            .setPopup(new mapboxgl.Popup()

            .setHTML(marker.properties.name))

            .addTo(map);        

        });

    });

},5000);

});
