Here's a modern solution using a promise:

<pre><code>function getAddress (latitude, longitude) {
 return new Promise(function (resolve, reject) {
 var request = new XMLHttpRequest();

 var method = 'GET';
 var url = 'http://maps.googleapis.com/maps/api/geocode/json?latlng=' + latitude + ',' + longitude + '&amp;sensor=true';
 var async = true;

 request.open(method, url, async);
 request.onreadystatechange = function () {
 if (request.readyState == 4) {
 if (request.status == 200) {
 var data = JSON.parse(request.responseText);
 var address = data.results[0];
 resolve(address);
 }
 else {
 reject(request.status);
 }
 }
 };
 request.send();
 });
};
</code></pre>

And call it like this:

<pre><code>getAddress(lat, lon).then(console.log).catch(console.error);
</code></pre>

The promise returns the address object in 'then' or the error status code in 'catch'

Same as @Sanchit Gupta.

in this part 

<pre><code>if (results[0]) {
 var add= results[0].formatted_address ;
 var value=add.split(",");
 count=value.length;
 country=value[count-1];
 state=value[count-2];
 city=value[count-3];
 x.innerHTML = "city name is: " + city;
}
</code></pre>

just console the results array

<pre><code>if (results[0]) {
 console.log(results[0]);
 // choose from console whatever you need.
 var city = results[0].address_components[3].short_name;
 x.innerHTML = "city name is: " + city;
}
</code></pre>

you can do it with pure php and google geocode api

<pre class="lang-php prettyprint-override"><code>/*
 *
 * @param latlong (String) is Latitude and Longitude with , as separator for example "21.3724002,39.8016229"

function getCityNameByLatitudeLongitude($latlong)
{
 $APIKEY = "AIzaXXXXXXXXXXXXXXXXXXXXXXXXXXX"; // Replace this with your google maps api key 
 $googleMapsUrl = "https://maps.googleapis.com/maps/api/geocode/json?latlng=" . $latlong . "&amp;language=ar&amp;key=" . $APIKEY;
 $response = file_get_contents($googleMapsUrl);
 $response = json_decode($response, true);
 $results = $response["results"];
 $addressComponents = $results[0]["address_components"];
 $cityName = "";
 foreach ($addressComponents as $component) {
 // echo $component;
 $types = $component["types"];
 if (in_array("locality", $types) &amp;&amp; in_array("political", $types)) {
 $cityName = $component["long_name"];
 }
 }
 if ($cityName == "") {
 echo "Failed to get CityName";
 } else {
 echo $cityName;
 }
}

<a href="https://www.bigdatacloud.com/" rel="nofollow noreferrer">BigDataCloud</a> also has a nice API for this, also for nodejs users.
they have <a href="https://www.bigdatacloud.com/geocoding-apis/free-reverse-geocode-to-city-api" rel="nofollow noreferrer">API for client - free</a>. But also <a href="https://www.bigdatacloud.com/geocoding-apis/reverse-geocode-to-city-api" rel="nofollow noreferrer">for backend</a>, using API_KEY (free according to quota).
<a href="https://github.com/bigdatacloudapi/nodejs-api-client" rel="nofollow noreferrer">Their GitHub page</a>.
the code looks like:
<pre><code>const client = require('@bigdatacloudapi/client')(API_KEY);

async foo() {
 ...
 const location: string = await client.getReverseGeocode({
 latitude:'32.101786566878445',

In case if you don't want to use google geocoding API than you can refer to few other Free APIs for the development purpose.
for example i used [mapquest] API in order to get the location name.
you can fetch location name easily by implementing this following function
<div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code> const fetchLocationName = async (lat,lng) =&gt; {
 await fetch(
 'https://www.mapquestapi.com/geocoding/v1/reverse?key=API-Key&amp;location='+lat+'%2C'+lng+'&amp;outFormat=json&amp;thumbMaps=false',
 )
 .then((response) =&gt; response.json())
 .then((responseJson) =&gt; {
 console.log(
 'ADDRESS GEOCODE is BACK!! =&gt; ' + JSON.stringify(responseJson),
 );
 });
 };</code></pre>
</div>
</div>

Is there a way to get a city name from a latitude and longitude point using the google maps api for javascript?

If so could I please see an example?

How can I get city name from a latitude and longitude point?
