How to create key/value array by normal array?

Here is the code and fiddle:

var config = function(){
    return {
        name: ["john", "lucy", "lily"],
        age: ["22", "21", "22"],
        gender: ["male", "female", "female"],
        people: function(index){
            index--;
            this.name = name[index];
            this.age = age[index];
            this.gender = gender[index];
        },
        people2: function(index){
            index--;
            this["name"] = name[index];
            this["age"] = age[index];
            this["gender"] = gender[index];
        },
    };
}();

alert(config.people(1).name);
alert(config.people2(1).name);

I can get the value by code like:

config.name[1];

I want to restructure a key/value array like:

{name:"john",age:22,gender:male}

The index value delegates the first, second and third people info. Can anyone help me to get the code working? I'm stuck!

If you still want to restructure the config object (smashing the arrays)

    var config = function(){
    return {
        name: ["john", "lucy", "lily"],
        age: ["22", "21", "22"],
        gender: ["male", "female", "female"],
        people: function(index){
            index--;
            this.name = this.name[index];
            this.age = this.age[index];
            this.gender = this.gender[index];
        },
    };
}();

config
***Object {name: Array[3], age: Array[3], gender: Array[3], people: function}
config.people(1)
config
***Object {name: "john", age: "22", gender: "male", people: function}

One possibility is, without changing much of your code, as follows:

var config = function(){
    var name = ["john", "lucy", "lily"],
        age = ["22", "21", "22"],
        gender = ["male", "female", "female"];
    return {
        people: function(index){
           return {
             name: name[index],
             age: age[index],
             gender: gender[index]
           }   
        }
    };
}();

You can return an object as a result

var config = function() {
  return {
    name: ["john", "lucy", "lily"],
    age: ["22", "21", "22"],
    gender: ["male", "female", "female"],
    people: function(index) {
      index--;
      return {
        name: this.name[index],
        age: this.age[index],
        gender: this.gender[index]
      };
    }
  };
}();

alert(config.people(1).name);
