Why is this variable undefined or not returned?

Question

I have the following code:

/*
 * converts a string to geolocation and returns it
 */

function stringToLatLng(string){
    if(typeof string == \"string\"){

Something like this:

function stringToLatLng(strloc, callback){
    if(typeof string == "string"){
        geocoder = new google.maps.Geocoder();
        geocoder.geocode( { 'address': strloc}, function(results, status) {
           if (status == google.maps.GeocoderStatus.OK) {
              callback.call({}, results[0].geometry.location);
           } else {
              console.log("Geocode was not successful for the following reason: " + status);
           }
        });
   }
}

stringToLatLng('New York', function(pos){
    console.log(pos);
});

In your code, when you return, you are actually returning from the function(results, status){..} function, not the stringToLatLng function, as said in the comments its an asynchronous call, so you must use a callback.
