How do I use the Geolocation API in JavaScript?

Answer

The Geolocation API in JavaScript allows you to access the geographical location of a device. Here's a simple example of how to use it to get the current position.

<!-- BEGIN COPY / PASTE -->
        if (navigator.geolocation) {
            navigator.geolocation.getCurrentPosition(
                (position) => {
                    console.log("Latitude: " + position.coords.latitude);
                    console.log("Longitude: " + position.coords.longitude);
                },
                (error) => {
                    console.error("Error Code = " + error.code + " - " + error.message);
                }
            );
        } else {
            console.error("Geolocation is not supported by this browser.");
        }
        <!-- END COPY / PASTE -->

Additional Comment:

The code checks if the Geolocation API is supported by the browser using "navigator.geolocation".
"getCurrentPosition" is called to get the current position, which takes two callback functions: one for success and one for error handling.
The success callback receives a "position" object containing "coords.latitude" and "coords.longitude".
The error callback handles any issues, such as user denial of location access.
Always ensure you handle errors gracefully and inform the user if geolocation is not supported.
