How can I determine the county of the United States by zip code?

Is it possible to implement a function on clientide in javascript to use it like this:

var county = get_county(zip_code);

I mean, is it possible to do this online through a script? Or do I need to dig a database? Or should I buy it?

Any help is appreciated!

PS
Using Dyrandz Famador I did this exercise for GAS:

function get_county(zip) {
 var county, response, result, adresses, i, j, n, type;
 response = Maps.newGeocoder().geocode(zip);
 for (i = 0; i < response.results.length; i++) {
   result = response.results[i];
   adresses = result.address_components;
   n = adresses.length;
   for (j=0;j<n;j++) {
     type = adresses[j].types[0];
     if (type == 'locality') county = (adresses[j].long_name);
     if (type == 'administrative_area_level_2')   {county =(adresses[j].long_name);}
   }
 }
 return (county);
}

you can use the google maps API to get locations from zip codes

Google API-, API .   , , Google   , .

, , API Google:

<script language="javascript" src="https://maps.google.com/maps/api/js?sensor=false"></script>

, :

<form>
zip: <input type="text" name="zip" value="46032"> <a href="#" onclick="getLocation()">Get Address</a>
</form>

, , "getLocation()" - :

...
<script language="javascript">
function getLocation(){
  getAddressInfoByZip(document.forms[0].zip.value);
}

function response(obj){
  console.log(obj);
}
function getAddressInfoByZip(zip){
  if(zip.length >= 5 && typeof google != 'undefined'){
    var addr = {};
    var geocoder = new google.maps.Geocoder();
    geocoder.geocode({ 'address': zip }, function(results, status){
      if (status == google.maps.GeocoderStatus.OK){
        if (results.length >= 1) {
      for (var ii = 0; ii < results[0].address_components.length; ii++){
        var street_number = route = street = city = state = zipcode = country = formatted_address = '';
        var types = results[0].address_components[ii].types.join(",");
        if (types == "street_number"){
          addr.street_number = results[0].address_components[ii].long_name;
        }
        if (types == "route" || types == "point_of_interest,establishment"){
          addr.route = results[0].address_components[ii].long_name;
        }
        if (types == "sublocality,political" || types == "locality,political" || types == "neighborhood,political" || types == "administrative_area_level_3,political"){
          addr.city = (city == '' || types == "locality,political") ? results[0].address_components[ii].long_name : city;
        }
        if (types == "administrative_area_level_1,political"){
          addr.state = results[0].address_components[ii].short_name;
        }
        if (types == "postal_code" || types == "postal_code_prefix,postal_code"){
          addr.zipcode = results[0].address_components[ii].long_name;

          addr.country = results[0].address_components[ii].long_name;
        }
      }
      addr.success = true;
      for (name in addr){
          console.log('### google maps api ### ' + name + ': ' + addr[name] );
      }
      response(addr);
        } else {
          response({success:false});
        }
      } else {
        response({success:false});
      }
    });
  } else {
    response({success:false});
