# Polygon With Hole

This example creates a polygon with an inner hole, by defining an inner path wound in the opposite direction to the outer path. Note that you can also use the Data layer, which offers a simpler way of creating holes because it handles the order of the inner and outer paths for you.

### TypeScript

```// This example creates a triangular polygon with a hole in it.

function initMap(): void {
document.getElementById("map") as HTMLElement,
{
zoom: 5,
center: { lat: 24.886, lng: -70.268 },
}
);

// Define the LatLng coordinates for the polygon's  outer path.
const outerCoords = [
{ lat: 25.774, lng: -80.19 },
{ lat: 18.466, lng: -66.118 },
{ lat: 32.321, lng: -64.757 },
];

// Define the LatLng coordinates for the polygon's inner path.
// Note that the points forming the inner path are wound in the
// opposite direction to those in the outer path, to form the hole.
const innerCoords = [
{ lat: 28.745, lng: -70.579 },
{ lat: 29.57, lng: -67.514 },
{ lat: 27.339, lng: -66.668 },
];

// Construct the polygon, including both paths.
paths: [outerCoords, innerCoords],
strokeColor: "#FFC107",
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: "#FFC107",
fillOpacity: 0.35,
});
bermudaTriangle.setMap(map);
}index.ts```

### JavaScript

```// This example creates a triangular polygon with a hole in it.
function initMap() {
const map = new google.maps.Map(document.getElementById("map"), {
zoom: 5,
center: { lat: 24.886, lng: -70.268 },
});
// Define the LatLng coordinates for the polygon's  outer path.
const outerCoords = [
{ lat: 25.774, lng: -80.19 },
{ lat: 18.466, lng: -66.118 },
{ lat: 32.321, lng: -64.757 },
];
// Define the LatLng coordinates for the polygon's inner path.
// Note that the points forming the inner path are wound in the
// opposite direction to those in the outer path, to form the hole.
const innerCoords = [
{ lat: 28.745, lng: -70.579 },
{ lat: 29.57, lng: -67.514 },
{ lat: 27.339, lng: -66.668 },
];
// Construct the polygon, including both paths.
paths: [outerCoords, innerCoords],
strokeColor: "#FFC107",
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: "#FFC107",
fillOpacity: 0.35,
});
bermudaTriangle.setMap(map);
}
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. */
html,
body {
height: 100%;
margin: 0;
}
style.css```
