javascript - Why is my recursive function call not returning a value? -


i have following code, trying return range between 2 numbers, , inner function not returning value. returns [function]. can tell me why?

var range = function(num1, num2) {     var output = [];       return function range2 () {         if (num2 - num1 === 2) {             return [num1+1];         }         else if (output.length + 1 === num2 - num1) {             return output;         }         else if (output.length + 1 !== num2 - num1) {             output.push(num1 + 1);         }         return range2(num1 + 1, num2);     }; };

//update: code ended working, fwiw:

var range = function(num1, num2) {     var list = [];     var range2 = function(num1, num2) {         list.push(num1 + 1);         if (num2 - num1 === 2) {             return list;         }         else {             return range2(num1 + 1, num2);         }     };     return range2(num1, num2); };

the range() function never calls range2(). returns function expression.

also, range2() needs take arguments.

var range = function(num1, num2) {    var output = [];      function range2(num1, num2) {      if (num2 - num1 === 2) {        return [num1 + 1];      } else if (output.length + 1 === num2 - num1) {        return output;      } else if (output.length + 1 !== num2 - num1) {        output.push(num1 + 1);      }      return range2(num1 + 1, num2);    };    return range2(num1, num2);  };    alert(range(1, 10));

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
