Writing Angular with Migration in Mind: Ex. 1

ServiceExample1.js

angular.module('myModule')
  .service('addresses', ['addressService', '$q', function(addressService, $q) {

    this.prefix = 'My Address: ';
    this.printAddress = function() {
      var deferred = $q.defer(),
          self = this;

      addressService.getFullAddress(function(addr) {
        deferred.resolve(self.prefix + addr);
      }, deferred.reject);

      return deferred.promise;
    };
  });
