Question

I have some simple OO code I’ve written that I’m playing with:

//define a constructor function
function person(name, sex) {
    this.name = name;
    this.sex = sex;

} 

//now define some instance methods
person.prototype.returnName = function() {
    alert(this.name);
}

person.prototype.returnSex = function() {
    return this.sex;
}

person.prototype.talk = function(sentence) {
    return this.name + ' says ' + sentence;
}

//another constructor
function worker(name, sex, job, skills) {
    this.name = name;
    this.sex = sex;
    this.job = job;
    this.skills = skills;
}

//now for some inheritance - inherit only the reusable methods in the person prototype
//Use a temporary constructor to stop any child overwriting the parent prototype 

var f = function() {};
f.prototype = person.prototype;
worker.prototype = new f();
worker.prototype.constructor = worker;

var person = new person('james', 'male');
person.returnName();
var hrTeamMember = new worker('kate', 'female', 'human resources', 'talking');
hrTeamMember.returnName();
alert(hrTeamMember.talk('I like to take a lot'));

Now this is all well and good. But I’m confused. I want to include namespacing as part of my code writing practice. How can I namespace the above code. As it is now I have 2 functions defined in the global namespace.

The only way I can think to do this is to switch to object literal syntax. But then how do I implement the pseudo-classical style above with object literals.

You could for example do following:

var YourObject;
if (!YourObject) {
  YourObject = {};

  YourObject.Person = function(name, sex) {
    // ...
  } 

  YourObject.Person.prototype.returnName = function() {
    // ...
  }

  // ...
}
