node.js - javascript use response from function in calling function -

i've got basic example of of node-geocoder, can't response bubble calling function

    var address = userupdates.address + " " + userupdates.city + ", " + userupdates.state + " " + userupdates.zip;     geocoder.geocode(address)         .then(function(res) {               console.log(res);         })         .catch(function(err) {              console.log(err);        }); 

the console.log produces correct json

[    {      latitude: 35,     longitude: -78.5,     country: 'united states',     city: 'clayton',     state: 'north carolina',     statecode: 'nc',     zipcode: '27520',     streetname: 'main st',     streetnumber: '100',     countrycode: 'us'     }  ] 

but can't assign res persist outside geocoder.geocode function

have tried creating global variable outside of geocoder.geocode function hold value?

   var globalres = null;    geocoder.geocode(address)         .then(function(res) {               globalres = res;               console.log(res);         })         .catch(function(err) {              console.log(err);        });
