How to create a custom InfoWindow with Google Maps and JavaScript?

To create a custom InfoWindow with Google Maps and JavaScript, we use the InfoWindow constructor.

For instance, we write

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

google.maps.event.addListener(
  marker,
  "mouseover",
  ((marker) => {
    return () => {
      const content = address;
      infowindow.setContent(content);
      infowindow.open(map, marker);
    };
  })(marker)
);

to call the InfoWindow constructor with an object with the content of the InfoWindow.

Then we add a mouseover event listener to the marker.

In the event listener, we have

infowindow.setContent(content)

to set the content of the InfoWindow to the content string.

And then we call open to open the InfoWindow on the marker on the map.

Conclusion

To create a custom InfoWindow with Google Maps and JavaScript, we use the InfoWindow constructor.
