### TypeScript

```typescript
// This example displays a map with the language set to Arabic and the
// regions set to Egypt. These settings are specified in the HTML script
// element when loading the Google Maps JavaScript API.
// Setting the language shows the map in the language of your choice.
// Setting the region biases the geocoding results to that region.
// In addition, the page's html element sets the text direction to
// right-to-left.
function initMap(): void {
  const cairo = { lat: 30.064742, lng: 31.249509 };

  const map = new google.maps.Map(
    document.getElementById("map") as HTMLElement,
    {
      scaleControl: true,
      center: cairo,
      zoom: 10,
    }
  );

  const infowindow = new google.maps.InfoWindow();

  infowindow.setContent("<b>القاهرة</b>");

  const marker = new google.maps.Marker({ map, position: cairo });

  marker.addListener("click", () => {
    infowindow.open(map, marker);
  });
}

declare global {
  interface Window {
    initMap: () => void;
  }
}
window.initMap = initMap;
```

### CSS

```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. 
 */
html,
body {
  height: 100%;
  margin: 0;
  padding: 0;
}
```

### HTML

```html
<html dir="rtl">
  <head>
    <title>Right-to-Left Languages</title>

    <link rel="stylesheet" type="text/css" href="./style.css" />
    <script type="module" src="./index.js"></script>
  </head>
  <body>
    <div id="map"></div>

    <!-- 
      The `defer` attribute causes the script to execute after the full HTML
      document has been parsed. For non-blocking uses, avoiding race conditions,
      and consistent behavior across browsers, consider loading using Promises. See
