TypeScript

let map: google.maps.Map;
async function initMap(): Promise<void> {
  const { Map } = await google.maps.importLibrary("maps") as google.maps.MapsLibrary;
  map = new Map(document.getElementById("map") as HTMLElement, {
    center: { lat: -34.397, lng: 150.644 },
    zoom: 8,
  });
}

initMap();
index.ts

JavaScript

let map;
async function initMap() {
    const { Map } = await google.maps.importLibrary("maps");
    map = new Map(document.getElementById("map"), {
        center: { lat: -34.397, lng: 150.644 },
        zoom: 8,
    });
}
initMap();
index.js

CSS

/* 
 * Always set the map height explicitly to define the size of the div element
 * that contains the map. 
 */
#map {
  height: 100%;
}

/* 
 * Optional: Makes the sample page fill the window. 
 */
