Get State,City name from a latitude and longitude

JavaScript and Geolocation

In our JavaScript, we can use getCurrentPosition() method to obtain user’s current location, but first, we need to know whether Geolocation API is available in the browser before we can continue.

Geolocation API is an important feature available in modern HTML5 web browsers, which allows us to request current location of the user using JavaScript, the location information is represented by latitude and longitude coordinates. For privacy reasons, the user permission is required to access its location information.
