如何在同一地图上使用带有多个标记的Google Maps API

function initMap() {
  const map = new google.maps.Map(document.getElementById("map"), {
    zoom: 10,
    center: { lat: -33.9, lng: 151.2 },
  });

  const locations = [
    { position: { lat: -33.89, lng: 151.21 }, title: "Marker 1" },
    { position: { lat: -33.88, lng: 151.22 }, title: "Marker 2" },
    { position: { lat: -33.87, lng: 151.23 }, title: "Marker 3" },
  ];

  locations.forEach((location) => {
    const marker = new google.maps.Marker({
      position: location.position,
      map: map,
      title: location.title,
    });
  });
}

<div id="map" style="width: 100%; height: 400px;"></div>
